1. When two cars with different masses collide head-on, which car experiences a greater change in momentum?

A. The car with the larger mass
B. The car with the smaller mass
C. Both cars experience the same change in momentum
D. It depends on the initial velocities of the cars

Correct answer: C

Rationale: In a head-on collision between two cars, the law of conservation of momentum states that the total momentum of the isolated system remains constant before and after the collision. The change in momentum of one car is equal in magnitude but opposite in direction to the change in momentum of the other car. As a result, both cars experience the same change in momentum during the collision. Choice A is incorrect because the change in momentum is the same for both cars due to the conservation of momentum principle. Choice B is incorrect as the smaller mass car does not experience a greater change in momentum. Choice D is incorrect as the initial velocities of the cars do not determine which car experiences a greater change in momentum; it is solely dependent on the masses of the colliding cars.

2. Based on the following passage, which of the following scenarios is correct?

A. The writer is a professional in a business environment.
B. The writer is a researcher writing for a scientific journal.
C. The writer is a student writing a first draft of a paper.
D. The writer is an author of literature.

Correct answer: B

Rationale: The passage uses precise, technical language typical of scientific writing, indicating the writer is a researcher. Choice A is incorrect as the passage does not reflect a business context. Choice C is incorrect as there is no indication that the writer is a student or in an academic setting. Choice D is incorrect as the content of the passage does not align with literature or creative writing.

3. What is the word 'principal' referring to in the following text?

A. Primary or chief
B. An acolyte
C. An individual who provides nurturing
D. One in a subordinate position

Correct answer: A

Rationale: In the provided text, 'principal' is referring to the primary or chief individual. The principal secretary for private affairs is considered second only to the treasurer, indicating a position of high importance. The term 'acolyte' (Choice B) refers to a ceremonial assistant, which does not fit the context. 'An individual who provides nurturing' (Choice C) and 'One in a subordinate position' (Choice D) do not accurately describe the role of the 'principal' in the text.

4. The author's purpose, major ideas, supporting details, visual aids, and vocabulary are the five key elements of what type of text?

A. Fictional texts
B. Narratives
C. Persuasive texts
D. Informational texts

Correct answer: D

Rationale: The author's purpose, major ideas, supporting details, visual aids, and vocabulary are key elements typically found in informational texts. Informational texts aim to inform and educate readers about a specific topic, which is why these elements are crucial for effectively conveying information in a clear and organized manner. Fictional texts focus more on storytelling and creativity rather than presenting facts and information, so they do not always include these specific elements. Narratives primarily focus on telling a story or recounting events, while persuasive texts aim to convince or sway the audience's opinion, so they may not always encompass all the elements mentioned in the question.

5. Anya was paid by Company X to analyze dwindling honeybee populations in the Southwest. After measuring hive populations over several months, she noticed no patterns in the geographic distributions of the deaths after comparisons with local maps of interest. This supported her hypothesis, so she took samples of the honey and the bees from the hives and performed dozens of dissections to confirm her suspicions. Which of the following is the most likely hypothesis upon which this research was performed?

A. Honeybees are being killed off, and their hives are destroyed by other extremely aggressive species of bees from the South.
B. Honeybees are contracting parasites in large droves.
C. Honeybees are so sensitive to certain pesticides that they die on contact.
D. Honeybees die in larger numbers around cell phone towers.

Correct answer: B

Rationale: The most likely hypothesis based on the information provided is that honeybees are contracting parasites in large droves. Anya observed no geographic patterns in hive deaths and proceeded to analyze honey and bees for further investigation. This suggests that she suspected a widespread issue affecting multiple hives simultaneously, consistent with a scenario where honeybees are being infected by parasites in high numbers, leading to dwindling populations across different locations. The other choices can be eliminated because there is no mention of aggressive species of bees from the South, no evidence pointing to pesticide sensitivity as the cause, and no indication of a correlation with cell phone towers in the information provided.
