1. Based upon the contextual evidence provided in the passage above, what is the meaning of the term enterprise in the third paragraph?

• A. Company
• B. Courage
• C. Game
• D. Cause

Correct answer: A

Rationale: In the third paragraph, the term 'enterprise' is used in the context of a group of travelers embarking on a journey together. In this context, 'enterprise' refers to a company or a group of people rather than courage, game, or cause. The word 'enterprise' is commonly used to denote a business organization or company, aligning with the idea of a group traveling together for a common purpose. 'Courage' and 'cause' do not fit the context of the travelers' journey, and 'game' is unrelated to the activities described in the passage.

2. What is the smallest bone in the human body?

• A. Stapes (Middle ear bone)
• B. Patella (Kneecap)
• C. Phalanges (Finger bones)
• D. Ribs

Correct answer: A

Rationale: The correct answer is A: Stapes (Middle ear bone). The stapes, located in the middle ear, is indeed the smallest bone in the human body. Despite its small size, the stapes is vital for hearing as it transmits and amplifies sound vibrations, contributing significantly to auditory perception. Choices B, C, and D are incorrect. The patella (kneecap) is the largest sesamoid bone in the human body, not the smallest bone. Phalanges are the bones in fingers and toes, not the smallest bone overall. Ribs are long bones that protect the chest cavity, not the smallest bone in the body.

3. Which of the following punctuation marks correctly completes the sentence below? "She bought several items for the trip____ a tent, a sleeping bag, and a flashlight."

• A. ;
• B. :
• C. ,
• D. .

Correct answer: B

Rationale: The correct punctuation mark to use in this sentence is the colon (:) because it is used to introduce a list. In this case, the list of items she bought for the trip includes a tent, a sleeping bag, and a flashlight. A semicolon (;) is not appropriate here because it is typically used to connect independent clauses. A comma (,) is not suitable as it would create a comma splice error. A period (.) is incorrect as it signifies the end of a sentence, which is not the intended purpose in this context.

4. Antigenic variation, a common strategy used by some viruses, allows them to:

• A. Produce toxins
• B. Evade the immune system
• C. Survive outside a host
• D. Replicate rapidly

Correct answer: B

Rationale: Antigenic variation is a strategy used by some viruses to evade the host's immune response. By constantly changing their surface antigens, viruses can avoid recognition and destruction by the immune system. This allows the virus to persist in the host and continue replicating, leading to prolonged infection and potential transmission to other hosts. Antigenic variation does not directly involve the production of toxins, survival outside a host, or rapid replication, making options A, C, and D incorrect in this context.

5. What is the functional group present in amines?

• A. Hydroxyl
• B. Carbonyl
• C. Amine
• D. Nitro

Correct answer: C

Rationale: The functional group present in amines is the amine group, represented as -NH2. Amines are organic compounds characterized by the presence of a nitrogen atom bonded to hydrogen atoms. The amine group distinguishes amines from other types of organic compounds, such as alcohols with the hydroxyl group, ketones with the carbonyl group, and nitro compounds with the nitro group. Therefore, the correct answer is 'C: Amine.'
