1. Select the pronoun that could be used in the following sentence: Mrs. Sato, _______ lives down the street, is 99 years old.

• A. she
• B. who
• C. which
• D. whom

Correct answer: B

Rationale: The correct answer is 'B' - 'who.' 'Who' is the correct relative pronoun to introduce the clause 'who lives down the street,' providing more information about Mrs. Sato. The other choices, 'she,' 'which,' and 'whom,' are not appropriate relative pronouns for referring to a person in this context.

2. Identify the determiner in the following sentence:

• A. happily
• B. branches
• C. few
• D. tree

Correct answer: C

Rationale: The determiner in the sentence is 'few.' Determiners specify the quantity or identity of a noun. In this case, 'few' indicates the number of birds present. Choice A, 'happily,' is an adverb modifying a verb or an adjective, not a determiner. Choice B, 'branches,' is a noun referring to parts of a tree, not a determiner. Choice D, 'tree,' is a noun identifying the main subject of the sentence, not a determiner.

3. What protein complex controls the progression of mitosis through its activation and degradation?

• A. Ribosome
• B. Cyclin-dependent kinase (CDK)
• C. Centriole
• D. Microtubule

Correct answer: B

Rationale: A) Ribosome: Ribosomes are cellular organelles responsible for protein synthesis and are not directly involved in controlling the progression of mitosis. B) Cyclin-dependent kinase (CDK): CDKs are a family of protein kinases that regulate the cell cycle, including the progression of mitosis. CDK activity is controlled by cyclins, which bind to CDKs to activate them at specific points in the cell cycle. The activation and degradation of cyclins regulate the activity of CDKs, which in turn control the progression of mitosis. C) Centriole: Centrioles are involved in organizing the microtubules of the mitotic spindle but do not directly control the progression of mitosis. D) Microtubule: Microtubules are structural components of the cytoskeleton and are involved in various cellular processes, including mitosis, but they do not control

4. What force causes an object to move in a circular path?

• A. Tension force
• B. Frictional force
• C. Centripetal force
• D. Gravitational force

Correct answer: C

Rationale: The centripetal force is the force responsible for keeping an object moving in a circular path. It is directed towards the center of the circle, providing the necessary inward acceleration to maintain the object's curved trajectory. Without this force, the object would move in a straight line tangent to the circle. Tension force, frictional force, and gravitational force are not the forces that cause an object to move in a circular path. Tension force is typically present in a string or rope and acts along the length of the material. Frictional force opposes the motion of an object relative to a surface, and gravitational force is the force of attraction between two masses.

5. What does 'mg' stand for in the metric system?

• A. microgram
• B. milligram
• C. gigabyte
• D. megagram

Correct answer: B

Rationale: 'mg' stands for milligram, which is equal to 1/1,000th of a gram. In the metric system, 'microgram' (choice A) is represented by 'mcg', 'gigabyte' (choice C) is a unit of digital information storage, and 'megagram' (choice D) is equivalent to a metric ton.
