All Questions (10)
A) To introduce the writer's main claim.
B) To provide support for the writer's claims.
C) To serve as the main commentary in an essay.
D) To replace the need for a clear line of reasoning.
Correct Answer: B
Essential Knowledge 1 states that 'Writers use evidence—facts, statistics, illustrations, and the like—to support their claims.' The primary role of evidence is to substantiate the assertions made by the writer.
A) It presents the evidence itself without interpretation.
B) It restates the claim in different words after the evidence is presented.
C) It explains how the provided evidence logically supports the writer's line of reasoning.
D) It attributes the evidence to its original source.
Correct Answer: C
Essential Knowledge 1 and 2 clarify that commentary's function is to establish the relationship between evidence and a claim by explaining how that evidence supports the argument. While attribution (D) is crucial for source integration, it is a separate function from commentary.
A) Dr. Evans's study shows that 67% of students felt less pressure.
B) This statistic, showing a clear majority of students benefiting, directly illustrates how a uniform policy can alleviate the social anxieties tied to fashion and brand-name apparel.
C) In another study, students reported that uniforms stifled their creativity.
D) Therefore, it is clear that school uniforms are a good idea for all schools.
Correct Answer: B
Effective commentary explains *how* the evidence supports the claim. Option B connects the 67% statistic directly to the idea of alleviating social anxiety, supporting the line of reasoning. Option A merely restates the evidence, C introduces an unrelated point, and D makes a hasty generalization.
A) As sociologist Dr. Anya Sharma argues in her 2022 book, 'The Digital Community,' social media has fundamentally altered teenage friendships (Sharma 45).
B) One expert notes that 'the attention economy rewards outrage over nuance' (Peters, 2021).
C) The economy has shifted. 'Over 40% of the workforce now participates in the gig economy.' This has major implications for the future.
D) According to a recent Pew Research Center study, a majority of Americans now get their news primarily from social media platforms.
Correct Answer: C
Option C presents a 'dropped quote' without any attribution. It is unclear who said or wrote the quoted sentence, violating the principle from Essential Knowledge 3 that writers must clearly and consistently attribute evidence. The other options provide attribution through a signal phrase (A, D) or a parenthetical citation (B).
A) Commentary
B) Line of reasoning
C) Plagiarism
D) Attribution
Correct Answer: D
Essential Knowledge 3 defines attribution as the act of clearly and consistently crediting sources. Commentary explains evidence, a line of reasoning is the argument's structure, and plagiarism is the failure to attribute.
A) To amplify a point made by the evidence.
B) To present new, unrelated evidence.
C) To clarify the meaning of a complex piece of data.
D) To qualify a claim by acknowledging the limits of the evidence.
Correct Answer: B
According to Essential Knowledge 2, commentary should explain the relationship between the *current* evidence and the claim. Its functions include illustrating, clarifying, amplifying, or qualifying a point. Introducing new, unrelated evidence within the commentary for a different piece of evidence would disrupt the line of reasoning.
A) The evidence provided does not support the claim.
B) The commentary makes a generalization that is too broad.
C) The evidence is presented as a 'dropped quote' with no attribution.
D) The claim is not clearly stated at the beginning of the paragraph.
Correct Answer: C
The paragraph includes a direct quotation without any signal phrase or citation to indicate its source. This is a classic example of a 'dropped quote' and a failure of attribution, which is a critical error in integrating sources according to Essential Knowledge 3. While the commentary might be slightly generalized (B), the lack of attribution is the most significant and fundamental flaw.
A) is more extensive and detailed than the evidence itself.
B) explicitly connects the chosen evidence back to the overarching claim.
C) introduces a new claim to be explored later in the essay.
D) uses the exact same wording as the claim to ensure consistency.
Correct Answer: B
The core function of commentary, as described in Learning Objective 1 and Essential Knowledge 1, is to explain the relationship between evidence and the claim. Therefore, effective commentary must explicitly connect the evidence to the claim it is meant to support, thereby strengthening the line of reasoning.
A) Place both the statistic and the anecdote in the introduction to prove the point immediately.
B) Use the statistic in the first body paragraph to establish a quantitative basis for the claim, then use the anecdote in a subsequent paragraph to provide a qualitative, humanizing perspective.
C) Place the anecdote first because stories are more interesting, and place the statistic in the conclusion as a final piece of proof.
D) Use only the statistic, as anecdotes are not considered valid evidence in academic writing.
Correct Answer: B
Essential Knowledge 2 emphasizes the *strategic selection and placement* of evidence. Option B demonstrates a sophisticated strategy by using hard data (statistic) to build a logical foundation and then following it with a compelling, illustrative anecdote. This creates a more robust and persuasive line of reasoning than the other options.
A) The writer will be accused of plagiarism because the source is not properly explained.
B) The reader may not understand how the evidence supports the writer's claim, weakening the line of reasoning.
C) The evidence will be considered invalid, regardless of its source or credibility.
D) The argument will be strengthened because the reader is allowed to interpret the evidence for themselves.
Correct Answer: B
The purpose of commentary is to explain the relationship between evidence and a claim (Learning Objective 1). Without commentary, the connection is not made explicit, and the reader is left to guess the writer's intention. This weakens the overall line of reasoning because the evidence is not effectively integrated to support the claim. While a lack of attribution leads to plagiarism (A), a lack of commentary is a failure of argumentation.
