In honor of his lost homeland, the exiled poet wrote a moving that described the beauty of his native country’s people, culture, and landscapes.
  1. A. elocution
  2. B. paean ✓
  3. C. oratory
  4. D. panegyric
Explanation: A 'paean' is a song of praise or triumph, often emotional and heartfelt—especially fitting for an exiled poet honoring his lost homeland. While 'panegyric' (D) also means a formal praise speech, 'paean' better conveys the personal, lyrical, and emotionally moving quality implied by 'moving' and reference to beauty of people/culture/landscapes.
🧪 AP Chemistry Medium
What is the final K ^{+} concentration in a solution made by mixing 300.0 mL of 1.0 M KNO _{3} and 700.0 mL of 2.0 M K _{3} PO _{4} ?
  1. A. 4.5 M
  2. B. 5.0 M
  3. C. 3.0 M ✓
  4. D. 2.0 M
Explanation: C —If the solute is an electrolyte, the solution will conduct electricity. Nonelectrolytes do not conduct electricity. Strong electrolytes conduct electricity extremely well. Weak electrolytes also conduct electricity, but not as well as a strong electrolyte.
📊 SAT Math Easy
Which choice most effectively uses data from the figure to complete the text? “The New York Tenement-House Evil and Its Cure” was written by Ernest Flagg for Scribner’s Magazine in 1894. In the piece, Flagg discusses the deplorable living conditions in the tenement housing developments, how the tenements came to be, and how the issue might be solved. A historian analyzing Flagg’s writing claims that Flagg believed that the primary motivation of those who built the tenement housing developments was to make money.
  1. A. have a generally greater average rate of change. ✓
  2. B. typically have a lower average rate of change.
  3. C. have approximately the same rate of change.
  4. D. are more likely to have a rate of change of zero.
Explanation: This question tests your ability to interpret rate of change from a graph. A steeper slope indicates a greater average rate of change. Since the lines in the figure are visibly steeper than the reference, they exhibit a higher rate of change. Choice B is incorrect because it suggests a flatter slope, which contradicts the visual data.
📖 SAT Reading & Writing Medium
The student wants to highlight two pumpkin varieties that can be consumed as food. 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. Blue, white, and orange pumpkins will often be found on the dinner table.
  2. B. Jarrahdale and Cinderella pumpkins are considered delicacies.
  3. C. Both Porcelain Doll and Casperita pumpkins can be eaten. ✓
  4. D. Porcelain Doll pumpkins are considered the most delicious pumpkin varietal.
Explanation: Focus on the specific claim—the student wants to show that there are two pumpkin varieties that can be eaten. Based on the notes, Casperita pumpkins are “edible” and Porcelain Doll pumpkins are a “good choice for pumpkin pie,” implying that they too are edible. So, choice (C) is the most logical option. The other options refer to pumpkins in the notes that are not consistently referred to as being edible.
🧬 AP Biology Hard
In a rural area of the country, there is a high incidence of a rare condition called methemoglobinemia, in which a mutation causes the skin of affected individuals to take on a bluish tint when under low oxygen conditions. All of the individuals with methemoglobinemia are descendants of one individual who immigrated to the area from another country. This is an example of
  1. A. natural selection.
  2. B. heterozygote advantage.
  3. C. bottleneck effect.
  4. D. founder effect. ✓
Explanation: Founder effect occurs when members of a population migrate to a new area and the frequency of one or more alleles in the migrating/founding population is higher than in the original population. Choice (A) is incorrect because there is no evidence that methemoglobinemia has a selective advantage, nor is there evidence that heterozygotes for the trait have a selective advantage, so choice (B) is also incorrect. The bottleneck effect occurs when a population undergoes a rapid and extreme decrease in population size, which is not the case in this example, so choice (C) is incorrect.
💻 AP Computer Science A Medium
A client program creates a Date object as follows.
  1. A. String s = d.toString();
  2. B. int x = d.day();
  3. C. Date e = d;
  4. D. Date e = new Date(1, 13, 2002);
  5. E. int y = d.year; ✓
Explanation: In Java, encapsulation restricts direct access to private fields. Since `year` is a private instance variable in the `Date` class, the client code in option (E) violates access control rules and will not compile. In contrast, options (A), (B), and (D) are valid because they use public methods or the constructor. Option (C) is also valid as it performs a reference assignment, which is permitted for objects of the same type.

💡 Study Tips

💚 Stay hydrated during study sessions

Even mild dehydration can reduce concentration and short-term memory. Keep a water bottle at your desk and take a sip during each break. Your brain is mostly water — it needs fuel to perform.

📖 Teach concepts using diagrams

Drawing concept maps, flowcharts, or diagrams helps you see relationships between ideas that aren't obvious in linear notes. This approach works for everyone and strengthens conceptual thinking.
