Passage I LITERARY NARRATIVE: This passage is adapted from the novel Skyward by Prakriti Basrai (©2012 by Prakriti Basrai). What or who is the “saving grace” referred to in the passage?
  1. A. Singer Stations and Service
  2. B. The narrator’s mother
  3. C. The narrator’s daughter
  4. D. Religious piety ✓
Explanation: The phrase "saving grace" refers to the narrator's deep religious devotion, which serves as her primary source of strength and moral guidance throughout the story. While her mother provides support and her daughter represents hope for the future, it is specifically her faith that acts as the spiritual anchor keeping her grounded during difficult times. This aligns with the passage's emphasis on how her spirituality sustains her when facing personal struggles or societal pressures.

What is the value of x in the equation 2^2 + 2^3 = 2^5?
  1. A. True
  2. B. False ✓
  3. C. Cannot be determined
  4. D. None of the above
Explanation: The equation is 2^2 + 2^3 = 4 + 8 = 12, while 2^5 = 32. Since 12 ≠ 32, the statement '2^2 + 2^3 = 2^5' is false. Therefore, x (implicitly representing the truth value of the equation) is False.
📖 SAT Reading & Writing Medium
The student wants to present general information about Dayton to an audience unfamiliar with it. Which choice most effectively uses relevant information from the notes to accomplish this goal? While researching a topic, a student has taken the following notes:
  1. A. The quick release mechanism on the ice cube tray is a useful invention, since prior to its creation, ice cubes would have to be removed from a tray using hot water.
  2. B. Charles Kettering, a Dayton resident, was a key figure in the development of automotive technology.
  3. C. Southwest Ohio city Dayton is the home of many useful inventions in fields ranging from aviation to consumer goods. ✓
  4. D. Without the contributions of Wilbur and Orville Wright, the famous inventors of the airplane, Dayton would not have the renown it presently does.
Explanation: Choice (C) is correct because it synthesizes the notes to provide a broad, general overview of Dayton's significance as a hub for various inventions, directly addressing the prompt's requirement to inform an unfamiliar audience. It effectively summarizes the specific examples in the notes—such as automotive technology and aviation—without getting bogged down in unnecessary details like the ice cube tray or hypothetical scenarios about what would happen without specific inventors. This choice successfully balances specificity with the broader context needed for a general presentation.
🧪 AP Chemistry Medium
The student did not have time to finish the experiment during the lab period and was forced to store the anhydrous salt and crucible in his lab drawer until the next day. At the beginning of the next lab period the student weighed the anhydrous salt and crucible. After calculating the percentage of water in the sample, the student found that the percentage was lower than predicted. Assuming all weighings were done correctly, what might be the cause of the lower-than-expected percentage?
  1. A. The sample dried further overnight.
  2. B. The student performed one or more weighings before the crucible had cooled to room temperature.
  3. C. The sample absorbed water from the air overnight. ✓
  4. D. The sample decomposed to another salt.
Explanation: C —Leaving the sample overnight in the lab drawer would cause the sample to be no longer anhydrous. The mass of the “anhydrous” salt would now be higher, indicating a smaller amount of water loss, which would lead to a lower percentage of water in the sample.
✍️ AP English Language Hard
The rhetoric in lines 10–11, describing what he did in the spring of 1845, implies mainly that Thoreau
  1. A. had a specific plan of action in mind.
  2. B. was determined to make a name for himself.
  3. C. acted impulsively. ✓
  4. D. had a devil-may-care attitude.
  5. E. had energy to spare.
Explanation: To some extent, each of the choices has some validity. Line 9, however, specifies that Thoreau was driven by “the normal anxieties and enthusiasms and rebellions of youth.”
💻 AP Computer Science A Medium
Suppose that addition and subtraction had higher precedence than multiplication and division. Then the expression
  1. A. 11
  2. B. 12
  3. C. 5 ✓
  4. D. 9
  5. E. −4
Explanation: If addition and subtraction had higher precedence, the expression $1 + 2 * 3 - 4 / 5$ would be evaluated as $((1 + 2) * (3 - 4)) / 5$. First, compute $1 + 2 = 3$ and $3 - 4 = -1$. Next, multiply these results: $3 * -1 = -3$. Finally, divide by 5. In Java, integer division truncates toward zero, so $-3 / 5$ results in $0$. However, looking at the provided options and the standard variation of this problem often involving $1 + 2 * 3 - 4 / 5$ yielding different results, let's.

💡 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.

🎯 Eliminate before you guess

On multiple-choice questions, crossing out answers you know are wrong before guessing dramatically improves your odds. Even eliminating one option on a four-choice question raises your chance from 25% to about 33%.
