Choose evidence you can explain
CHAPTER 31
Choose evidence you can explain
A famous example is not useful just because the reader recognizes the name. Evidence becomes valuable when you know enough detail to connect it directly to the claim. Two developed examples can carry more reasoning than five references that appear for a sentence and disappear before they prove anything.
Choose evidence with usable detail
Before selecting a piece of evidence, ask whether you know enough specific detail about it to develop a full paragraph, not just enough to name it in passing. An example you can only gesture at will not support the kind of explanation a strong argument paragraph requires.
Match the example to the claim you are making
An example should connect directly to the specific claim a paragraph is making, not to the general topic the essay is about. A historical event related to risk in general is not automatically evidence for a specific claim about risk and significant achievement unless the connection is made explicit.
Use history only when you know the mechanism
A historical example is useful only when you can explain the specific mechanism connecting the event to your claim, not just the event's outcome. Naming a historical figure or event without explaining how it actually functions as evidence leaves the connection to the reader to guess.
Use personal evidence without overgeneralizing it
A personal experience can be strong evidence when it is specific and the essay is honest about its limits. Personal evidence becomes weak when a single experience is presented as though it proves a claim true for everyone, rather than as one specific, well-explained case.
Use current events only when the facts are secure
A current event makes useful evidence only when you are confident about its actual details. An essay that gets the facts of a recent event wrong undermines its own credibility, so uncertain recollection of a current event is often less reliable evidence than a well-known historical case or a careful hypothetical.
Use a hypothetical as reasoning, not fake history
A hypothetical can test the logic of a claim, but it should be labeled as hypothetical and never disguised as an event that actually occurred. Because Row B rewards specific evidence supporting claims, use a verifiable example when you have one; use a hypothetical mainly to clarify a principle, limit, or counterexample.
Reject evidence that needs too much setup
If an example requires several sentences of pure background before it can even begin to connect to the claim, it may not be the most efficient choice available. Evidence that reaches the claim quickly, with detail that does real work rather than merely orienting the reader, usually serves a timed essay better.
Keep enough detail for the commentary to work
An example stated too briefly leaves the commentary that follows with nothing specific to explain. Keeping enough concrete detail in the evidence itself, not just in the surrounding commentary, gives the explanation something real to work with.

EXAM DIAMOND Choose evidence you know well enough to develop, not evidence that is merely recognizable. Two well-explained examples usually carry more reasoning than five names that never connect to the claim. |

EXAM DIAMOND The argument rubric does not require a fixed mix of evidence types or a set number of examples. Use evidence you know well enough to explain accurately. |
CONSTRUCTED-RESPONSE DRILLS
These drills use the risk-taking prompt from Chapter 30.
Drill 1: Add usable detail to a thin reference
Draft evidence: “Many inventors throughout history took big risks, like Thomas Edison.”
This reference names a recognizable figure but lacks usable detail. Revise it into evidence specific enough to support a full paragraph of commentary.
Model reasoning: A revision might read: “In 1879, Edison and his Menlo Park team tested more than 1,600 materials in the search for a practical filament, part of a larger effort to build a commercially usable electric-lighting system. The example shows sustained investment in experimentation without a guaranteed result.” This version supplies a specific mechanism, extended team experimentation across many tested materials, that the following commentary can actually explain, rather than a bare name the reader is left to fill in independently.
Drill 2: Distinguish hypothetical reasoning from disguised invention
Draft evidence: “In 1850, a young entrepreneur named James Whitfield risked his family's savings on a failed textile venture before eventually succeeding, teaching the whole town a valuable lesson about perseverance.”
Explain why this evidence is problematic as written, and revise it to use hypothetical reasoning honestly.
Model reasoning: This evidence presents an invented figure and story as though it were verified historical fact, which risks the essay's credibility if a reader recognizes the fabrication. A revision might instead frame it explicitly as reasoning: “Consider a hypothetical entrepreneur who risks a family's savings on a new venture: even if the first attempt fails, the specific knowledge gained about the market and about her own capacities may make a second, better-informed attempt more likely to succeed than a first attempt would have been.” This version uses the same underlying logic without disguising invention as documented history.
CHAPTER 31 PRACTICE
These questions use the risk-taking prompt from Chapter 30. Answer all six questions before checking explanations.
Question 1
- AA. “In 1879, Edison and his Menlo Park team tested more than 1,600 materials in the search for a practical filament, part of a larger effort to build a commercially usable electric-lighting system.”
- BB. “Thomas Edison took risks and succeeded.”
- CC. “Many famous inventors have been risk-takers throughout history.”
- DD. “Edison is a name everyone recognizes.”
Question 2
- AA. Personal evidence is never acceptable in an argument essay
- BB. The evidence is too specific and detailed
- CC. Sports-related evidence cannot be used in argument essays
- DD. It overgeneralizes a single specific experience into a universal claim about everyone, rather than presenting it as one well-explained case
Question 3
- AA. Historical examples are inherently less persuasive than other types of evidence
- BB. Without explaining how the decision specifically connects to the outcome, the reader is left to guess the connection between the historical event and the claim, weakening the evidence's actual argumentative force
- CC. Only economic history can be used as evidence in argument essays
- DD. Historical examples must always be more than one hundred years old
Question 4
- AA. Including the current event regardless of uncertainty, since recency always outweighs accuracy
- BB. Including the current event but adding several unrelated additional examples to compensate
- CC. Avoiding all current events as evidence permanently, in every essay
- DD. Avoiding the current event in favor of a more securely known example, since a current event is useful evidence only when the writer is confident about its actual details
Question 5
- AA. “Consider a hypothetical entrepreneur who risks a family's savings on a new venture: even if the first attempt fails, the knowledge gained may make a second attempt more likely to succeed.”
- BB. “In 1850, a young entrepreneur named James Whitfield risked his family's savings on a failed textile venture before eventually succeeding.”
- CC. “Historical records definitively prove that risk-taking always leads to eventual success.”
- DD. “Everyone knows that taking risks eventually pays off for entrepreneurs.”
Question 6
- AA. The evidence is factually inaccurate
- BB. The evidence is not related to the essay's general topic
- CC. The evidence may not be the most efficient choice available, since evidence that reaches the claim quickly with detail that does real work usually serves a timed essay better than evidence requiring extensive setup
- DD. The evidence should be replaced with a personal anecdote instead
ANSWERS AND EXPLANATIONS
Show the answers and explanations
1. Correct answer: A
A (correct): This evidence supplies a specific mechanism and concrete detail, sustained team experimentation across many tested materials, that later commentary can actually explain and connect to the claim.
B: This is a bare, recognizable name attached to a vague claim without the specific detail a full paragraph of commentary would need to work with.
C: This vague generalization names no specific person or mechanism at all, providing no usable detail for commentary to develop.
D: This statement about recognizability provides no substantive detail about what Edison actually did or how it connects to the claim about risk.
2. Correct answer: D
A: Personal evidence can be strong when specific and honest about its limits; the problem here is the overgeneralization, not the use of personal evidence itself.
B: The evidence as described lacks specific detail about the actual tryout experience; the stated problem is overgeneralization, not excessive specificity.
C: No topic category is inherently prohibited; the issue is the overgeneralized claim drawn from one experience, not the subject matter itself.
D (correct): This is exactly the problem this chapter's fourth subtitle addresses: personal evidence becomes weak when one specific experience is stretched into a claim about all people in all situations.
3. Correct answer: B
A: This chapter does not rank evidence types against each other in this way; the concern is whether the mechanism connecting evidence to claim is explained, not the category of evidence used.
B (correct): A historical example supports the claim only when the writer explains the mechanism connecting the event to the argument. Naming a familiar event is not enough.
C: No such restriction exists; the chapter's guidance about mechanism applies broadly to historical evidence in general, not to a single narrow category.
D: No such age requirement exists in this chapter's guidance; the relevant standard is whether the mechanism connecting evidence to claim is understood and explained.
4. Correct answer: D
A: This contradicts the chapter's guidance, which specifically warns that factual errors in current event evidence undermine an essay's credibility.
B: Adding more examples does not address the underlying problem of factual uncertainty in the current event evidence itself.
C: The chapter does not recommend a permanent ban on current events; it recommends using them only when the facts are securely known, which varies by situation.
D (correct): If the writer is unsure of the facts of a current event, the example can introduce an avoidable error. A securely known example is safer under timed conditions.
5. Correct answer: A
A (correct): This version explicitly signals that the example is a reasoned hypothetical, “consider a hypothetical entrepreneur,” rather than presenting invented specifics as though they were verified historical fact.
B: This presents an invented figure and specific date as though they were documented historical fact, which is exactly the disguised invention this chapter warns against.
C: This makes an overstated factual claim without any actual historical specificity, which is a different problem from properly framing a hypothetical.
D: This vague generalization provides no reasoning structure at all, hypothetical or otherwise, and does not model the honest hypothetical framing this chapter recommends.
6. Correct answer: C
A: Nothing indicates the evidence is inaccurate; the concern is efficiency and setup cost, not factual accuracy.
B: The evidence does eventually connect to the claim; the concern is how much setup is required to reach that connection, not a lack of topical relevance.
C (correct): Evidence that needs a long setup before it reaches the claim is inefficient under time. Choose an example whose relevant facts can be established quickly.
D: This chapter does not recommend a specific replacement evidence type; it recommends reconsidering evidence that requires excessive setup, regardless of what type would replace it.
