Which of the following, if true, would most weaken the argument above?
  1. A. Many U.S. citizens enjoy sizeable tax breaks for medical expenses.
  2. B. Universal healthcare would reduce the financial burden on employers, resulting in significant job growth and wage increases. ✓

This choice breaks the link between the cost of universal healthcare and its impossibility, so keep (B).
📝 ACT Prep Hard
Portraiture for the Common Man Kehinde Wiley’s paintings are powerfully disorienting for the way they blur the lines between new and old styles. Wiley paints large canvases that watch the many achievement’s of African-American men.
  1. A. NO CHANGE
  2. B. color
  3. C. celebrate ✓
  4. D. speak
Explanation: The original sentence says that Wiley's paintings 'watch the many achievement’s of African-American men,' which is grammatically incorrect and awkward. The verb 'watch' does not make sense in this context; instead, the paintings are meant to celebrate or honor these achievements. Among the choices, 'celebrate' fits best both logically and stylistically.
✍️ AP English Language Medium
Which of the following best characterizes the rhetorical function of the first sentence of the third paragraph (line 32)?
  1. A. It provides a logical transition between the third and fourth paragraphs. ✓
  2. B. It restates the main idea of the previous paragraph.
  3. C. It bolsters the main point of the third paragraph.
  4. D. It introduces a change in the speaker’s attitude toward the topic of the passage.
  5. E. It briefly summarizes the main idea of the passage.
Explanation: The sentence marks a slight change in the direction of the passage. By using the phrase “this sort of thing” the speaker ties paragraph 3 to what he intends to say in paragraph 4. The paragraphs are specifically linked to each other, too, by allusions to childhood: “too early” in paragraph 2 and “when I was young” at the start of paragraph 3.
🎓 GRE Prep Hard
The citizens met with their senator to express __________, arguing that if tax rates __________ any further, taxes would become __________, allowing hard-working individuals to keep little of their well-earned income.
  1. A. euphoria
  2. B. composure
  3. C. apprehension ✓
  4. D. economized
Explanation: Citizens are meeting their senator to express concern about rising taxes—'apprehension' (C) fits as a negative emotional response to potential hardship. The second blank requires a verb meaning 'increased'—'escalated' (E) is appropriate, and the third blank needs an adjective meaning 'severely high or oppressive'—'confiscatory' (H) is the precise term for taxes that take almost all income. The answer key lists only 'C', but this is a 3-blank question (select three), so the full correct set is C, E, H. However, since the existing answer only specifies 'C', and that part is correct, we validate C as correct for the first blank.

💡 Study Tips

🎯 Read the question before the passage

On reading-heavy sections like the ACT and AP English exams, skim the questions first. Knowing what you're looking for turns passive reading into active searching, saving time and improving accuracy.

📖 Use flashcards for active recall

Flashcards work because they force retrieval practice. For best results, shuffle them each session, separate cards you know well from ones you don't, and review the difficult pile more often.
