What this skill covers
This skill covers sentence-level editing (subject-verb agreement, sentence completeness, punctuation) and short revision tasks like choosing the piece of evidence that most directly supports a given claim.
For evidence-selection questions, the correct choice is the option that most directly measures the exact outcome named in the claim — a related but indirect fact is usually the tempting wrong answer.
Worked examples
Example 1
Choose the grammatically correct sentence.
A. Each of the reports includes a summary.
B. Each of the reports include a summary.
C. Each of the reports including a summary.
D. Each of the reports have included a summary yesterday.
Why: "Each" is singular, so "includes" (not "include") is the correct verb form.
Example 2
A paragraph argues that a new recycling program increased participation. Which evidence best supports the claim?
A. A city audit found participation rose from 30% to 52% of households after the program began.
B. The recycling bins are green.
C. The city has many neighborhoods.
D. Some residents own reusable bags.
Why: This directly measures the exact outcome the claim is about (participation rate, before and after) rather than an unrelated or indirect fact.
