1. How do vaccines primarily function within the body?

• A. Creating a physical barrier against pathogens
• B. Triggering an inflammatory response
• C. Developing immunological memory to a specific pathogen
• D. Activating phagocytes to engulf pathogens

Correct answer: C

Rationale: Vaccines primarily function by stimulating the immune system to develop immunological memory to a specific pathogen. When a vaccine is administered, it exposes the immune system to a harmless version of a pathogen or a piece of it. This exposure triggers the immune response, leading to the production of antibodies and memory cells specific to that pathogen. Choice A is incorrect because vaccines do not create a physical barrier; rather, they prepare the immune system to recognize and fight specific pathogens. Choice B is incorrect as vaccines do trigger an immune response, but the primary goal is to create memory rather than inflammation. Choice D is incorrect as vaccines do not directly activate phagocytes; instead, they stimulate the immune system to generate a targeted response against a particular pathogen.

2. How many millimeters are in 0.75 centimeters?

• A. 7.5 mm
• B. 0.75 mm
• C. 75 mm
• D. 75 cm

Correct answer: C

Rationale: To convert centimeters to millimeters, you need to multiply by 10 since there are 10 millimeters in a centimeter. Therefore, 0.75 centimeters equals 0.75 x 10 = 7.5 millimeters, not 75 millimeters (Choice C). Choice A (7.5 mm) is the correct conversion, while Choice B (0.75 mm) and Choice D (75 cm) are incorrect conversions.

3. Which word is most closely synonymous with the word 'patronage' as it appears in the following statement? '...that I am sure he will need no charitable aid or condescending patronage.'

• A. Auspices
• B. Aberration
• C. Acerbic
• D. Adulation

Correct answer: A

Rationale: The correct answer is 'Auspices.' 'Auspices' is closely related to 'patronage' in the sense of support or sponsorship. In the context of the excerpt, it conveys the idea that the working man will not require condescending support or sponsorship but will actively participate and contribute to the Institute. The other choices are incorrect: 'Aberration' means a deviation from the norm, 'Acerbic' means sharp or bitter in tone, and 'Adulation' means excessive admiration or praise, none of which align with the meaning of 'patronage' in this context.

4. How do organisms maintain homeostasis?

• A. By increasing their body temperature, blood pH, and fluid balance.
• B. By undergoing biochemical processes and absorbing energy to increase entropy.
• C. By undergoing biochemical processes to maintain the order of their external environment.
• D. By using free energy and matter via biochemical processes to work against entropy.

Correct answer: D

Rationale: Organisms maintain homeostasis by utilizing free energy and matter through biochemical processes to counteract entropy, which helps in preserving internal stability. This process involves maintaining a balance within the organism's internal environment despite external changes, ensuring proper functioning and survival. Choice A is incorrect because increasing body temperature, blood pH, and fluid balance alone do not define the comprehensive process of maintaining homeostasis. Choice B is incorrect as absorbing energy to increase entropy goes against the concept of maintaining internal stability. Choice C is incorrect as maintaining the order of the external environment does not directly contribute to the organism's internal stability and balance.

5. Which of these examples is a compound sentence?

• A. Alex and Shane spent the morning coloring and later took a walk down to the park.
• B. After coloring all morning, Alex and Shane spent the afternoon at the park.
• C. Alex and Shane spent the morning coloring, and then they took a walk down to the park.
• D. After coloring all morning and spending part of the day at the park, Alex and Shane took a nap.

Correct answer: C

Rationale: Option C is a compound sentence because it consists of two independent clauses joined by a coordinating conjunction ('and then'). The first independent clause is 'Alex and Shane spent the morning coloring,' and the second independent clause is 'they took a walk down to the park.' Choices A, B, and D are not compound sentences. In choice A, although there are two actions mentioned, they are not independent clauses; they are part of a single sentence. Choice B is a complex sentence with a dependent clause ('After coloring all morning') and an independent clause. Choice D is a complex sentence with a compound predicate ('After coloring all morning and spending part of the day at the park') followed by an independent clause.
