1. Which of the following is NOT a route of transmission for a sexually transmitted infection (STI)?

• A. Unprotected sexual contact
• B. Sharing contaminated needles
• C. Deep kissing
• D. Mother to child during childbirth

Correct answer: C

Rationale: Rationale: A) Unprotected sexual contact is a common route of transmission for sexually transmitted infections (STIs) as many STIs are spread through genital, anal, or oral sex without the use of barrier protection such as condoms. B) Sharing contaminated needles can also transmit STIs such as HIV and hepatitis B and C, especially among individuals who inject drugs. C) Deep kissing, while it can transmit certain infections like herpes simplex virus (HSV-1) or cytomegalovirus (CMV), is not a common route of transmission for most STIs. D) Mother to child transmission during childbirth can occur with certain STIs such as HIV, syphilis, and herpes, where the infection can be passed from the mother to the baby during delivery. Therefore, deep kissing (option C) is the correct answer as it is not a typical route of transmission for most STIs.

2. According to the passage, learning from history can help us

• A. predict future events with complete certainty.
• B. avoid any possibility of making mistakes in the present.
• C. identify potential challenges and develop innovative solutions.
• D. directly replicate the successes of past societies in our own time.

Correct answer: C

Rationale: The passage emphasizes learning from both successes and failures, identifying potential obstacles, and using historical knowledge to create solutions for current problems.

3. In the phrase "a drop in the bucket," "bucket" represents:

• A. A literal container
• B. A large quantity
• C. A specific goal
• D. An obstacle

Correct answer: B

Rationale: The phrase signifies that something is insignificant compared to a much larger amount.

4. What is the meaning of the idiom "to cross that bridge when we come to it"?

• A. To deal with a problem immediately
• B. To plan for the future in detail
• C. To worry about potential problems prematurely
• D. To avoid difficult situations

Correct answer: C

Rationale: The idiom suggests dealing with challenges as they arise, not before.

5. In the reaction 2Na + 2H2O → 2NaOH + H2, what is the limiting reactant when 3 moles of sodium react with 2 moles of water?

• A. Na
• B. H2O
• C. NaOH
• D. H2

Correct answer: a

Rationale: Sodium is the limiting reactant because it runs out first in a 1:1 ratio with water.

6. Dense irregular connective tissue, found in tendons and ligaments, provides:

• A. Flexibility
• B. Lubrication
• C. Insulation
• D. Tensile strength

Correct answer: D

Rationale: The correct answer is D: 'Tensile strength.' Dense irregular connective tissue is composed of tightly packed collagen fibers arranged in a random pattern, providing resistance to tension forces. This structural arrangement is ideal for tendons and ligaments, as they need to withstand pulling and stretching forces. 'Flexibility' (A) is more characteristic of elastic fibers, 'Lubrication' (B) is provided by synovial fluid in joints, and 'Insulation' (C) is typically associated with adipose tissue. Therefore, tensile strength is the primary function of dense irregular connective tissue in tendons and ligaments.
