1. Which of the following types of immunity is provided by the secretion of antibodies by B-cells?

• A. Cell-mediated
• B. Humoral
• C. Innate immunity
• D. Phagocytic

Correct answer: B

Rationale: The correct answer is B: Humoral. Humoral immunity involves B-cells secreting antibodies to fight pathogens. In this type of immunity, antibodies circulate in the blood and other body fluids to neutralize pathogens and prevent infections. Cell-mediated immunity, on the other hand, involves the activation of T-cells to directly attack infected or abnormal cells, not the secretion of antibodies. Innate immunity refers to the nonspecific defense mechanisms the body has in place from birth, such as physical barriers and inflammatory responses. Phagocytic immunity is not a recognized type of immunity; phagocytosis is a mechanism used by cells like macrophages to engulf and digest pathogens, but it is not a specific form of immunity like humoral or cell-mediated immunity.

2. In a lesson on mass media, a teacher is showing commercials and analyzing their hidden messages. Which of the following is an example of a commercial that claims professional authority not supported by evidence?

• A. A commercial selling pain relief featuring a professional basketball player who says he uses the product
• B. A commercial for cold medicine narrated by a man in a doctor's coat
• C. A commercial for a new toy showing footage of children playing happily with it
• D. A commercial for a prepared food with testimonials by real consumers

Correct answer: B

Rationale: The commercial for cold medicine narrated by a man in a doctor's coat is the correct answer. This commercial claims professional authority without providing any evidence of the narrator's credentials. While the man may appear to be a doctor with his coat, there is no proof that he is actually a medical professional or that the product is recommended by experts. This lack of evidence can mislead consumers by giving the product an air of legitimacy and credibility without factual support. Choices A, C, and D do not fit the criteria as they involve a professional athlete endorsing a product, children enjoying a toy, and real consumers providing testimonials respectively.

3. How many feet are in 9 yards?

• A. 45 ft
• B. 18 ft
• C. 36 ft
• D. 27 ft

Correct answer: D

Rationale: To convert yards to feet, you need to know that 1 yard is equal to 3 feet. Therefore, to find out how many feet are in 9 yards, you multiply 9 by 3, which equals 27 feet. Choice A (45 ft) is incorrect as it miscalculates by multiplying 9 by 5 instead of 3. Choice B (18 ft) incorrectly multiplies 9 by 2. Choice C (36 ft) is incorrect as it doubles the answer of 18 feet, which is also an incorrect calculation.

4. Complete the following equation: 5 + 3 × 4 - 6 / 2 = ?

• A. 5
• B. 9
• C. 11
• D. 7

Correct answer: B

Rationale: To solve this equation, follow the order of operations (PEMDAS/BODMAS): First, perform multiplication and division from left to right. 3 × 4 equals 12, and 6 / 2 equals 3. Then, carry out addition and subtraction from left to right. 5 + 12 - 3 equals 14, not 9. Therefore, the correct answer is 14, making choice B the correct answer. Choices A, C, and D can be eliminated as they do not match the correct result obtained by following the order of operations.

5. Julia Robinson, an avid photographer in her spare time, was able to capture stunning shots of the local wildlife on her last business trip to Australia. Which of the following is an adjective in the preceding sentence?

• A. Time
• B. Capture
• C. Avid
• D. Photographer

Correct answer: C

Rationale: The correct answer is 'C: Avid.' In the sentence, 'avid' describes Julia Robinson as someone who is enthusiastic and passionate about photography in her spare time. Adjectives are words that modify or describe nouns, and in this case, 'avid' modifies the noun 'photographer.' Choice A, 'Time,' is a noun and does not describe or modify any other word in the sentence. Choice B, 'Capture,' is a verb indicating an action taken by Julia Robinson. Choice D, 'Photographer,' is a noun identifying the role or occupation of Julia Robinson, not describing her in this context.
