guess

A guess is when you try to answer something, but you don't know the full answer.

It's like when you see a wrapped present and try to say what's inside.

You are not sure, but you say what you think it is.

This is a guess.

A guess is when you try to answer something even if you don't know the full truth. Imagine you see a wrapped present. You can guess what is inside, but you aren't completely sure. You are making an attempt to figure it out without all the facts. It's like taking a shot in the dark, hoping you're right. So, if someone asks you a question and you're not certain, you might say, "I'll take a guess!"

A guess, at its core, is when you try to answer a question or form an opinion even if you don't have all the facts. Imagine someone asks you to name a song playing, and you haven't heard it before – any answer you give would be a guess.

It's about making an educated assumption or a random shot in the dark when you lack complete information. You're essentially taking a chance on what the answer might be, rather than stating something you know for sure.

A 'guess' at the B2 level refers to a hypothesis or conjecture made without complete information. It implies an informed estimation rather than a random shot in the dark, often based on prior knowledge, context, or intuition. While there's an element of uncertainty, a B2-level guess suggests a more reasoned attempt to deduce an answer or predict an outcome. It's distinct from a wild assumption, as it often involves weighing probabilities or interpreting incomplete data. Therefore, making a guess at this level demonstrates an ability to engage with ambiguity and formulate plausible ideas.

§ What does 'guess' mean?

Definition
A guess is an attempt to give an answer or an opinion when you are not certain of the facts. It is used when you try to identify something without having all the information.

The word 'guess' is often used when you are not sure about the answer to a question. It means you are making an estimate or a judgment without complete knowledge. For example, if someone asks you how old a person is and you don't know, you might make a guess.

My guess is that the meeting will start at 10 AM.

§ Where you hear 'guess'

You will hear the word 'guess' in many different places, from everyday conversations to more formal settings.

  • At Work: In a work environment, 'guess' can be used when discussing projections, potential outcomes, or when someone is unsure about a detail. For instance, a manager might ask for a 'best guess' on when a project will be finished.
  • At School: Students often use 'guess' when they are answering questions they are not entirely certain about. Teachers might also encourage students to 'take a guess' if they are stuck.
  • In the News: News reports sometimes use 'guess' when talking about future events or uncertain situations, such as predictions about the economy or election results.

The newspaper made a guess about the election results before they were announced.

Understanding 'guess' is helpful because it allows you to express uncertainty or to acknowledge that you are providing an estimate rather than a definitive answer. It's a common and very useful word in English.

You are a detective investigating a complex case with limited evidence. Write a short report outlining your initial 'guess' about the perpetrator's motive and identity, explaining what led you to this preliminary conclusion despite the lack of concrete facts.

Well written! Good try! Check the sample answer below.

Sample answer

Based on the cryptic clues and the victim's past associations, my preliminary guess points towards a disgruntled former business partner. The pattern of previous incidents involving the victim suggests a motive rooted in revenge or professional jealousy. While concrete evidence is still forthcoming, my intuition is that the perpetrator sought to inflict not just financial harm, but also public humiliation. This is, of course, purely a hypothesis at this stage, requiring further investigation to corroborate.

Sample answer

My guess, regarding the artist's enigmatic use of color and form, is that they are attempting to visually represent the inherent chaos and beauty within human consciousness. The juxtaposition of vibrant hues against stark, angular lines seems to symbolize the internal struggle between our rational and emotional selves. While this interpretation is largely conjecture on my part, the inherent ambiguity of the piece invites such subjective analyses, allowing viewers to project their own experiences onto the canvas.

Good morning, everyone. Today, I'd like to present a theoretical guess regarding the anomalous energy readings we've observed in the recent experiments. My postulation is that these fluctuations are indicative of a previously uncatalogued subatomic particle, interacting with the existing field in a manner we haven't yet accounted for. While this remains largely unsubstantiated, the initial data points strongly suggest a need to explore this hypothesis further, and I believe extensive validation will either confirm or refute this initial proposition.

What is the primary characteristic of the scholars' attempts to interpret the manuscript?

Read this passage:

The ancient manuscript, discovered deep within the catacombs, presented an undecipherable script. Scholars offered numerous interpretations, each a carefully considered guess, attempting to unlock its secrets. The prevailing theory, although lacking definitive proof, posited that the text was a forgotten chronicle of a lost civilization, detailing their advanced astronomical knowledge and spiritual practices. The sheer complexity of the symbols, however, meant that any definitive translation remained elusive, leaving the true meaning open to continued conjecture.

What is the significance of 'educated guesses' in theoretical physics, as described in the passage?

Read this passage:

In the realm of theoretical physics, scientists often formulate educated guesses, or hypotheses, to explain observed phenomena before empirical evidence can fully validate them. These initial propositions are crucial for guiding experiments and research. One such guess, concerning the existence of dark matter, has revolutionized our understanding of the universe's composition, even though its direct detection remains an ongoing challenge. Without these informed conjectures, scientific progress would be significantly hampered.

The detective had to make an educated ___ based on the sparse clues available at the crime scene.

正解! おしい! 正解: conjecture

In this context, 'conjecture' best fits the idea of forming an opinion or theory without conclusive proof, which aligns with an 'educated guess'. 'Speculation' is similar but often implies less foundation. 'Hypothesis' is more scientific and formal, while 'surmise' is a verb.

fill blank C2

Despite the economist's detailed analysis, the future of the stock market remains largely a matter of wild ___.

正解! おしい! 正解: guesswork

'Wild guesswork' perfectly captures the idea of making an estimate without any reliable basis, which is appropriate for unpredictable market behavior. 'Presumption' implies taking something for granted, 'arbitrariness' refers to randomness, and 'hunch' is more of an intuitive feeling.

fill blank C2

The curator admitted that the precise age of the ancient artifact was merely a ___ on their part, awaiting further scientific verification.

正解! おしい! 正解: supposition

'Supposition' means an uncertain belief or an assumption, which accurately reflects a curator's tentative statement about an artifact's age before definitive proof. 'Approximation' and 'estimation' suggest a more calculated process, and 'guesstimate' is a more informal blend of guess and estimate.

fill blank C2

Without concrete data, any proposed solution for the complex environmental problem would be little more than a shot in the ___.

正解! おしい! 正解: dark

'A shot in the dark' is an idiom meaning an attempt to guess something without having enough information or knowledge. This fits the context of proposing a solution without concrete data.

fill blank C2

It was a sheer ___ of fortune that allowed them to find the hidden treasure, as they had no map or specific directions.

正解! おしい! 正解: fluke

'Fluke' refers to an unlikely chance occurrence, especially a surprising piece of luck, which aligns well with finding treasure without any guidance. 'Hap' is an older term for chance, 'contingency' is a future event that is possible but not certain, and 'fortuity' is a chance event.

fill blank C2

The meteorologist's long-range forecast was, by his own admission, a rather speculative ___ given the inherent unpredictability of atmospheric patterns.

正解! おしい! 正解: conjecture

While 'prediction' and 'prognosis' are related, 'conjecture' best captures the idea of a statement based on incomplete information and personal judgment, especially when the meteorologist admits it's 'speculative'. 'Speculation' is the act, 'conjecture' is the outcome.

multiple choice C2

The detective’s initial ______ about the perpetrator’s motive proved to be surprisingly prescient, despite the paucity of evidence at the crime scene.

正解! おしい! 正解: conjecture

While 'guess' is a general term, 'conjecture' specifically implies an opinion or conclusion formed on the basis of incomplete information, often with a more formal or intellectual nuance, fitting the C2 level context of a detective's thought process. 'Postulate' implies a fundamental assumption, and 'hypothesis' is a testable explanation, neither of which perfectly fit the nuanced meaning of a tentative conclusion. 'Guess' is too informal for C2.

multiple choice C2

Despite her meticulous research, the economist's prediction about the stock market's trajectory remained largely a ______ based on complex, yet inherently unpredictable, variables.

正解! おしい! 正解: prognostication

'Prognostication' refers to the action of foretelling or prophesying a future event, often with an element of informed but not entirely certain prediction, which aligns well with the complexity and inherent uncertainty of economic forecasting at a C2 level. 'Guess' is too informal. 'Calculation' implies certainty from data, and 'deduction' implies logical inference from premises.

multiple choice C2

The art historian's audacious ______ regarding the provenance of the recently discovered painting, though lacking definitive proof, sparked a vibrant debate within the academic community.

正解! おしい! 正解: surmise

'Surmise' means to suppose that something is true without having evidence to confirm it, which captures the essence of a well-considered, but unproven, opinion in an academic context at a C2 level. 'Guess' is too simplistic. 'Assertion' and 'declaration' imply a stronger, more confident statement, which doesn't fit the 'lacking definitive proof' aspect.

true false C2

A 'guess' at a C2 level can be used interchangeably with a 'well-reasoned hypothesis' when discussing scientific methodology.

正解! おしい! 正解: 間違い

While both involve forming an idea without complete certainty, a 'guess' is typically informal and less structured, whereas a 'well-reasoned hypothesis' in scientific methodology implies a testable, formulated explanation based on existing knowledge and observation, which is a much higher level of intellectual rigor. They are not interchangeable at a C2 level.

true false C2

In formal academic discourse at a C2 level, it is generally acceptable to refer to a tentative conclusion as 'just a guess'.

正解! おしい! 正解: 間違い

At a C2 level, especially in formal academic discourse, more precise and sophisticated terminology like 'conjecture,' 'hypothesis,' 'postulation,' or 'preliminary finding' would be expected when referring to a tentative conclusion. 'Just a guess' is too informal and lacks the necessary academic gravitas.

true false C2

The term 'guess' at a C2 level can sometimes imply an intuitive or instinctive judgment, even if unsupported by explicit evidence.

正解! おしい! 正解: 正しい

Even at a C2 level, 'guess' can indeed encompass an intuitive or instinctive judgment, particularly in contexts where formal reasoning is impossible or impractical, and one relies on 'gut feeling' or implicit pattern recognition. This aligns with the idea of attempting an answer without being certain of all the facts.

Imagine you are an investigative journalist tasked with uncovering a complex financial scandal. Describe the challenges you face in separating fact from speculation and the strategies you employ to avoid making premature guesses in your reporting. Focus on the ethical implications of publishing unverified information.

Well written! Good try! Check the sample answer below.

Sample answer

As an investigative journalist delving into a labyrinthine financial scandal, the primary challenge lies in meticulously disentangling verified facts from unsubstantiated speculation. The pressure to break a story can often tempt one to make premature guesses, but journalistic integrity demands rigorous verification. My strategy involves cross-referencing multiple independent sources, scrutinizing financial documents, and conducting extensive interviews, always prioritizing corroboration over speed. The ethical implications of publishing unverified information are profound; a single erroneous guess can irrevocably damage reputations, incite market instability, and erode public trust. Therefore, due diligence and a steadfast commitment to accuracy are paramount, even if it means delaying publication to ensure every detail is irrefutably substantiated.

Discuss the role of intuition versus empirical evidence in scientific discovery. When is a 'guess' or a hypothesis a valuable starting point, and when does it become a hindrance to objective research? Provide examples from scientific history.

Well written! Good try! Check the sample answer below.

Sample answer

In the realm of scientific discovery, the interplay between intuition and empirical evidence is complex and often symbiotic. A 'guess' or a nascent hypothesis frequently serves as a crucial starting point, providing a directional beacon for inquiry. For instance, Kekulé's 'dream' of snakes biting their tails led to the correct guess about the benzene ring structure. However, this intuitive leap only becomes scientifically valuable when subjected to rigorous empirical testing. Conversely, when intuition supplants objective research, it can become a significant hindrance, leading to confirmation bias or the perpetuation of unsubstantiated theories. The scientific method, therefore, acts as a crucial arbiter, demanding that all guesses, no matter how inspired, must ultimately withstand the crucible of experimentation and demonstrable evidence to gain legitimacy.

Analyze the philosophical concept of epistemic humility, particularly in the context of forming opinions or making 'guesses' about complex societal issues. How does acknowledging the limits of one's knowledge contribute to more informed and less dogmatic discourse?

Well written! Good try! Check the sample answer below.

Sample answer

Epistemic humility, the recognition of the inherent limitations of one's own knowledge, is a foundational philosophical concept crucial for navigating complex societal issues and for informing our 'guesses' or opinions. In a world saturated with information, the temptation to form strong, dogmatic opinions based on incomplete data is pervasive. However, embracing epistemic humility fosters a more nuanced and less confrontational discourse. By acknowledging the possibility that one's initial guess might be incomplete or even incorrect, individuals become more open to alternative perspectives and new evidence, mitigating the impact of cognitive biases. This intellectual modesty prevents the ossification of viewpoints and promotes a continuous, collaborative search for more comprehensive understanding, ultimately leading to more informed and less polarized discussions.

According to the passage, what distinguishes a compelling literary analysis from a less effective one?

Read this passage:

In the annals of literary criticism, the act of interpretation often teeters on the precipice between insightful deduction and speculative conjecture. A critic's 'guess' about an author's intent or a character's motivations, while potentially illuminating, risks imposing a subjective framework onto a text that may resist such neat categorization. The most compelling analyses, therefore, are those that meticulously anchor their interpretations in textual evidence, rather than allowing unfettered speculation to dictate meaning. This disciplined approach acknowledges the inherent ambiguity of art while striving for a robust, defensible understanding.

According to the passage, what distinguishes a compelling literary analysis from a less effective one?

正解! おしい! 正解: Its careful grounding of interpretations in textual evidence.

What is the primary role of an 'informed guess' or theoretical model in astrophysics?

Read this passage:

The field of astrophysics frequently grapples with phenomena that defy direct observation, necessitating an almost philosophical reliance on informed 'guesses' or theoretical models. From the nature of dark matter to the origins of the universe, scientists construct elaborate frameworks based on indirect evidence and mathematical inference. While these conjectures are invaluable for guiding research, they are continually subjected to rigorous testing and refinement as new data emerges. The scientific ethos demands that even the most elegant guess must eventually be corroborated by empirical validation, or else it remains within the realm of hypothesis.

What is the key difference between a 'guess' and an inference in a legal context?

Read this passage:

In legal proceedings, the distinction between a 'guess' and an inference is paramount. While a guess is often unmoored from factual basis, an inference is a logical deduction drawn from established facts, even if those facts are circumstantial. Jurors are frequently instructed to avoid speculation and to base their verdicts solely on the evidence presented. The legal system, therefore, strives to eliminate arbitrary guesses, demanding instead a reasoned and evidence-based conclusion, thereby upholding the principle of justice and fairness.

What is the key difference between a 'guess' and an inference in a legal context?

正解! おしい! 正解: A guess lacks a factual basis, while an inference is a logical deduction from facts.
