1. 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.

2. What is 0.02 as a ratio?

• A. 1:50
• B. 1:20
• C. 2:100
• D. 4:20

Correct answer: C

Rationale: To convert 0.02 to a ratio, you need to express it as a fraction. 0.02 is equivalent to 2/100. Simplifying this fraction gives you 1/50. So, the correct ratio for 0.02 is 1:50. Choice A is correct because it accurately represents the ratio of 0.02. Choices B, C, and D are incorrect: B is not the simplified form of 0.02, C simplifies to 1:50, not 2:40, and D is not the correct simplified ratio for 0.02.

3. Hampton was born and raised in Maywood, a suburb of Chicago, Illinois, in 1948. Which revision best improves the sentence?

• A. NO CHANGE
• B. in Maywood, of Chicago, Illinois in 1948.
• C. in Maywood, of Chicago, Illinois, in 1948.
• D. in Chicago, Illinois of Maywood in 1948.

Correct answer: C

Rationale: The corrected choice C 'in Maywood, of Chicago, Illinois, in 1948.' is the best revision as it places commas around the city and state, as well as around the year, improving clarity and readability. Choice A is incorrect as it does not provide the necessary punctuation for clarity. Choice B incorrectly places 'of Chicago' between 'Maywood' and 'Illinois,' disrupting the flow of information. Choice D reverses the order of 'Chicago, Illinois' and 'Maywood,' making it structurally incorrect.

4. What is the primary function of B cells in the immune system?

• A. Directly attacking and engulfing pathogens
• B. Producing antibodies specific to a pathogen
• C. Destroying infected body cells
• D. All of the above

Correct answer: B

Rationale: B cells are a type of white blood cell that primarily functions by producing antibodies specific to a pathogen. These antibodies play a crucial role in marking pathogens for destruction by other immune cells. While B cells are essential for the immune response, they do not directly attack and engulf pathogens or destroy infected body cells. These functions are carried out by other immune cells like macrophages and cytotoxic T cells. Therefore, the correct answer is B, as it accurately reflects the primary role of B cells in the immune system.

5. 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.
