1. Select the correct verb to complete the following sentence: I _________ about it for a long time before I decided to major in criminal justice.

• A. think
• B. thank
• C. thinked
• D. thought

Correct answer: D

Rationale: The correct answer is 'thought.' 'Thought' is the correct past tense form of 'think.' In this sentence, 'thought' is used to indicate that the thinking process happened in the past before deciding to major in criminal justice. Choices A, B, and C are incorrect. 'Think' is the present tense form, 'thank' is a different verb with a different meaning, and 'thinked' is not a valid past tense form of 'think.'

2. Which type of tissue protects the respiratory system's trachea?

• A. Bone
• B. Cartilage
• C. Collagen
• D. Keratin

Correct answer: B

Rationale: Cartilage is the correct answer as it provides flexible support and protection in the trachea. Cartilage is specifically designed to maintain the trachea's shape and prevent it from collapsing during breathing. Bone is a rigid tissue, not found in the trachea, and would not provide the necessary flexibility for breathing. Collagen is a structural protein but does not offer the same support and flexibility as cartilage in this context. Keratin is a protein that forms structures like hair and nails, and it is not present in the trachea to provide protection.

3. 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.

4. Which of the following is a logical conclusion that can be drawn from the information in the passage above?

• A. Victor's long reign provided the opportunity for her to bring balance to England and right the wrongs that had occurred during the reigns of her uncles.
• B. It was the death of Princess Charlotte Augusta that motivated the remaining princes to marry and start families.
• C. The Duke of Kent had hoped for a son but was delighted with his good fortune in producing the surviving heir that his brothers had failed to produce.
• D. King William IV was unreasonably suspicious of the Duchess of Kent's motivations, as she cared only for her daughter's well-being.

Correct answer: B

Rationale: The correct answer is B. The passage mentions that after the death of Princess Charlotte Augusta, the remaining princes considered marrying and starting families since her death left the succession undetermined. Choice A is incorrect because the passage does not provide information about Victoria's reign bringing balance or righting any wrongs during her uncles' reigns. Choice C is incorrect as there is no mention of the Duke of Kent having a preference for a male heir or being disappointed with a female heir. Choice D is incorrect as the passage does not give details about King William IV's suspicions towards the Duchess of Kent or her motivations.

5. What is the purpose of the periosteum, the tough outer layer of bone?

• A. Produces red blood cells
• B. Provides protection and nourishment to bone
• C. Forms the joint surface
• D. Stores minerals

Correct answer: B

Rationale: The periosteum, the tough outer layer of bone, serves the purpose of providing protection to the bone and nourishing it through the blood vessels it contains. It acts as a protective layer for the bone structures. Choices A, C, and D are incorrect because the periosteum does not produce red blood cells (which is the function of bone marrow), form joint surfaces (which is typically the role of articular cartilage), or store minerals (which is primarily done by bone tissue itself and not the periosteum).
