1. A scientist needs 12 mL of a solution. They have a bottle with 12L in it. Do they have enough?

• A. Yes, they have exactly what they need
• B. Yes, they have more than what they need
• C. No, they do not have enough
• D. None of the above

Correct answer: B

Rationale: 1 liter has 1000 milliliters. To convert from milliliters to liters, the decimal point moves three places to the left. So, the bottle has 12000 mL of solution, which is a lot more than the required 12 mL. Therefore, the scientist has more than what they need. Choice A is incorrect as the bottle has more than the required amount. Choice C is incorrect as the bottle contains significantly more solution than needed. Choice D is incorrect as the scientist does have more than enough solution.

2. Select the word that makes the following sentence grammatically correct. Mary Ann gave ______ credit for studying so hard and passing the test.

• A. oneself
• B. itself
• C. herself
• D. themselves

Correct answer: C

Rationale: The correct answer is 'C: herself.' In this sentence, 'herself' is the reflexive pronoun that correctly refers back to Mary Ann. It shows that Mary Ann is giving credit to herself for studying hard and passing the test. The use of 'oneself' (choice A) would be incorrect here as it is too general and does not specify Mary Ann. Choices B and D ('itself' and 'themselves') are also incorrect because they do not match the singular subject 'Mary Ann.' Therefore, 'herself' is the only option that fits both grammatically and contextually in this sentence.

3. A worker in a warehouse ships 9 boxes each day. If every box must contain 3 shipping labels, how many shipping labels does the worker need each day?

• A. 24 labels
• B. 27 labels
• C. 20 labels
• D. 30 labels

Correct answer: B

Rationale: To find the total number of shipping labels needed, multiply the number of boxes by the labels per box: 9 boxes * 3 labels per box = 27 labels. Therefore, the worker needs 27 shipping labels each day. Choice A, 24 labels, is incorrect because it results from multiplying 9 boxes by 3 labels without calculating the correct total. Choice C, 20 labels, is incorrect as it underestimates the total number of labels needed. Choice D, 30 labels, is incorrect as it overestimates the total by multiplying incorrectly.

4. Which of the following organisms would not have eukaryotic cells?

• A. Bacteria
• B. Dog
• C. Human
• D. Onion

Correct answer: A

Rationale: The correct answer is A, Bacteria. Bacteria do not have eukaryotic cells. They are single-celled organisms with prokaryotic cells. Dogs, humans, and onions are all multicellular organisms that possess eukaryotic cells. Therefore, choices B, C, and D have eukaryotic cells and are not the correct answer.

5. In the solid state, you would expect a nonmetal to be _________.

• A. brittle
• B. lustrous
• C. malleable
• D. conductive

Correct answer: A

Rationale: In the solid state, you would expect a nonmetal to be brittle. Nonmetals generally lack the malleability and ductility of metals, which makes them prone to being brittle and easily fractured under stress. This property is due to the lack of metallic bonding in nonmetals, which results in a more rigid and less flexible structure. Choice B, 'lustrous,' is incorrect because nonmetals typically do not exhibit a shiny or reflective surface like metals do. Choice C, 'malleable,' is also incorrect as nonmetals lack the ability to be hammered or rolled into thin sheets like metals. Choice D, 'conductive,' is incorrect since nonmetals are generally poor conductors of electricity compared to metals.
