📝 Questions

✍️ AP English Language Hard
All of the following interpretations explain the rhetorical purpose in line 21 of capitalizing “Time” and “Distance” EXCEPT
  1. A. to support the narrator’s previous claim that on long flights “distance and time are the same” (line 20). ✓
  2. B. to indicate that suddenly becoming airborne is the equivalent of a metaphysical moment that, in effect, transforms reality.
  3. C. in the context, to emphasize the significance of the moment when the plane became airborne.
  4. D. to imply that during a solo flight Time and Distance assume the stature of a deity in the mind of a pilot.
  5. E. to suggest that Time and Distance become virtually palpable during the experience of flying solo.
Explanation: All the other choices are feasible interpretations, but not (A), which, in the context, is virtually impenetrable.
📖 SAT Reading & Writing Medium
Which of the following would be points at which the function y = ( x + 4) ( x − 5) x intersects the x axis?
  1. A. I only
  2. B. II only
  3. C. I and III only
  4. D. I, II, and III ✓
Explanation: All of the options have a y value of 0. So, look at what values of x will cause there to be a y value of 0, since a point that intersects the x axis must have a y value of 0. In y = ( x + 4) ( x − 5) x , if x is 0, −4, or 5, the entire right side of the equation would be 0. Therefore, all three options would be points at which the function intersects the x axis.
🧬 AP Biology Medium
Which of the following best summarizes the relationship between hydrolysis and dehydration reactions?
  1. A. Hydrolysis builds monomers, and dehydration reactions break down monomers.
  2. B. Hydrolysis breaks down polymers into monomers, and dehydration reactions link monomers to form polymers. ✓
  3. C. Hydrolysis reactions release water into the environment, and dehydration reactions consume water from the environment.
  4. D. Hydrolysis reactions only occur in carbohydrates and proteins, and dehydration reactions only occur in lipids and nucleic acids.
Explanation: Hydrolysis uses water to break down polymers into monomers, and dehydration synthesis combines monomers into polymers while removing a water molecule. Choice (A) is incorrect because hydrolysis does not build monomers nor does dehydration synthesis break down monomers. Hydrolysis reactions consume, not release, water, so choice (C) is incorrect. All macromolecules, not just carbohydrates and proteins, can be broken down by hydrolysis reactions, so choice (D) is incorrect.
🧪 AP Chemistry Medium
Determine the wavelength of light with and energy of 9.98 × 10 ^{–19} J.
  1. A. 1.99 × 10 ^{–7} m ✓
  2. B. 5.03 × 10 ^{6} m
  3. C. 4.51 × 10 ^{23} m
  4. D. 1.98 × 10 ^{–43} m
Explanation: A —The AP Exam gives two equations for use in the question. These questions are: E = hν and c = λν . The constants are also listed. The constants are h = 6.626 × 10 ^{–34} J s and c = 2.998 × 10 ^{8} m s ^{–1} .
📝 ACT Prep Hard
In the figure below, AB is perpendicular to BC, LO is equal to 4, MO is equal to ON, and LM is equal to 6. What is MN?
  1. A. √13 ✓
  2. B. √20
  3. C. √25
  4. D. √30
  5. E. √36
Explanation: Since AB ⊥ BC, triangle LMO is a right triangle. Given LO = 4 and LM = 6, we can find MO using the Pythagorean theorem: MO² = LM² - LO² = 6² - 4² = 36 - 16 = 20, so MO = √20. Since MO = ON, ON = √20. Now, in right triangle MNO, MN² = MO² + ON² = (√20)² + (√20)² = 20 + 20 = 40, so MN = √40 = 2√10. However, looking at the answer choices, the closest match is √13, which suggests a different interpretation or calculation error in the original explanation. But based on the given information and standard geometric principles, the calculation should lead to √40 = 2√10, which is not among the choices. The question may have an error in the answer choices or the problem setup.
📊 SAT Math Hard
11. Sunjay is traveling to a national park. The number of miles he needs to travel can be represented by the equation M = 172 − 57 h, where M is the the number of miles to the national park and h is the number of hours Sunjay has to travel. What is the meaning of the value 57 in this equation?
  1. A. Sunjay started at a distance 57 miles from the national park.
  2. B. Sunjay will reach the national park in 57 hours.
  3. C. Sunjay travels to the national park at a rate of 57 miles per hour. ✓
  4. D. Sunjay has traveled 172 miles in 57 hours.
Explanation: Getting to the Answer: (A) is incorrect per the analysis. (B) is incorrect because h is the number of hours, not 57 (which is an absurd value as well). The analysis shows that 57 is the number of miles traveled each hour, so (C) is correct.

💡 Study Tips

💚 Don't multitask while studying

Switching between studying and your phone, social media, or TV fragments your attention and dramatically reduces what you retain. Put your phone in another room during focused study blocks.

📖 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.
