1. While studying vocabulary, a student notices that the words circumference, circumnavigate, and circumstance all begin with the prefix 'circum'. The student uses her knowledge of affixes to infer that all of these words share what related meaning?

• A. Around, surrounding
• B. Travel, transport
• C. Size, measurement
• D. Area, location

Correct answer: A

Rationale: The correct answer is A: 'Around, surrounding.' The prefix 'circum-' commonly means 'around' or 'surrounding,' as observed in words like circumference (the distance around a circle), circumnavigate (to sail or travel around something), and circumstance (a condition surrounding or related to an event). Choices B, C, and D are incorrect because the shared meaning among these words is related to being around or surrounding, not travel, transport, size, measurement, area, or location.

2. Which of the following is a common characteristic of alkynes?

• A. They have a triple bond between carbon atoms.
• B. They are saturated hydrocarbons.
• C. They contain only single bonds.
• D. They are aromatic compounds.

Correct answer: A

Rationale: The correct answer is A. Alkynes are hydrocarbons characterized by at least one triple bond between carbon atoms. This triple bond sets them apart from alkanes, which only have single bonds, and alkenes, which feature at least one double bond. The presence of a triple bond makes alkynes unsaturated hydrocarbons. Choice B is incorrect as alkynes are unsaturated hydrocarbons, not saturated. Choice C is incorrect because alkynes contain at least one triple bond, making them different from compounds with only single bonds. Choice D is incorrect because aromatic compounds have a distinct cyclic structure with resonance stabilization, a feature not shared by alkynes.

3. What would be the most helpful advice for the student starting a research assignment on Japanese-American internment camps during World War II?

• A. Conduct a broad internet search to get a wide view of the subject.
• B. Consult an American history textbook.
• C. Find websites about Japanese culture such as fashion and politics.
• D. Locate texts in the library related to World War II in America and look for references to internment camps in the index.

Correct answer: D

Rationale: The best advice for the student would be to locate texts in the library related to World War II in America and look for references to internment camps. This choice is the most appropriate as it focuses on accessing specific and credible sources directly related to the research topic. Choices A and C are too broad and may not provide in-depth information on the internment camps. Choice B, while related to American history, may not offer the specific details needed for the research assignment on Japanese-American internment camps during World War II.

4. Which structure do cells rely on for movement?

• A. Flagellum
• B. Microtubule
• C. Pili
• D. Vesicle

Correct answer: A

Rationale: The correct answer is A: Flagellum. Cells rely on flagella for movement, which are whip-like structures that propel the cell forward through their whipping motion. Flagella provide motility to single-celled organisms and certain cells in multicellular organisms. Microtubules, on the other hand, provide structural support to the cell and play a role in intracellular transport. Pili are short, hair-like structures used for attachment to surfaces or other cells, not for movement. Vesicles are membrane-bound sacs involved in intracellular transport, aiding in the movement of substances within the cell, but not in the movement of the cell itself.

5. Choose the sentence with correct punctuation and formatting:

• A. Throughout the song, he says “Remember the better days” and he gives examples.
• B. Throughout the song, he says, “Remember the better days,” and he gives examples.
• C. Throughout the song, he says Remember the better days, and he gives examples.
• D. Throughout the song, he says Remember the better days and he gives examples.

Correct answer: B

Rationale: The correct answer is B because it uses proper punctuation and formatting with the quotation marks around the phrase 'Remember the better days' and a comma after it to indicate the continuation of the sentence. This follows standard grammar rules for punctuating quotes within a sentence. Choice A lacks a comma after the quoted phrase, which is needed before the conjunction 'and.' Choices C and D have missing or misplaced commas and lack proper quotation marks around the quoted phrase, making them incorrect in terms of punctuation and formatting.
