1. What is the meaning of the idiom 'to bite off more than one can chew'?

• A. To be overly confident
• B. To take on more than one can handle
• C. To be easily discouraged
• D. To be meticulous in planning

Correct answer: B

Rationale: The correct answer is B: 'To bite off more than one can chew' means to take on more than one can handle or to undertake a task exceeding one's capabilities. This idiom warns against overcommitting oneself and facing difficulties in managing the workload effectively. Choice A, 'To be overly confident,' is incorrect as the idiom implies a situation of overestimating one's capacity rather than confidence. Choice C, 'To be easily discouraged,' is not related to the idiom's meaning, which focuses on task difficulty rather than emotional response. Choice D, 'To be meticulous in planning,' is not accurate as the idiom refers to the execution of tasks rather than the planning phase.

2. Which of the following functions is not controlled by the autonomic nervous system?

• A. Digestion
• B. Walking
• C. Heartbeat
• D. Temperature regulation

Correct answer: B

Rationale: The correct answer is B: Walking. Walking is not directly controlled by the autonomic nervous system. Walking is a voluntary action governed by the somatic nervous system, which controls voluntary skeletal muscle movement. The autonomic nervous system, on the other hand, regulates functions that are involuntary, such as digestion, heartbeat, and temperature regulation. Choices A, C, and D are all functions controlled by the autonomic nervous system. Digestion involves processes like peristalsis and secretion of digestive enzymes, heartbeat is regulated by the autonomic nervous system to maintain blood pressure and circulation, and temperature regulation includes responses like sweating or shivering to maintain body temperature within a narrow range.

3. Which of the following best describes the author’s purpose?

• A. The author wants to tell customers about the cars available at Carl’s Car Depot.
• B. The author wants to encourage other car dealerships to lower their prices.
• C. The author wants to provide new and used cars at affordable prices.
• D. The author wants to attract customers to Carl’s Car Depot.

Correct answer: D

Rationale: The author's purpose is to attract customers to Carl's Car Depot. The text from the extract clearly emphasizes the one-day-only summer sale event at Carl’s Car Depot, highlighting the wide range of cars available at discounted prices with special financing options. The author aims to draw in potential customers by presenting compelling offers and creating a sense of urgency. Choices A, B, and C are incorrect because the primary focus is on attracting customers to Carl’s Car Depot by showcasing the available cars and the limited-time sale, not solely informing customers about the cars, urging other dealerships to lower prices, or generally providing affordable cars.

4. How can you distinguish between these three types of graphs - scatterplots: Quadratic, Exponential, Linear?

• A. Linear: straight line; Quadratic: U-shape; Exponential: rises or falls quickly in one direction
• B. Linear: curved line; Quadratic: straight line; Exponential: horizontal line
• C. Linear: zigzag line; Quadratic: U-shape; Exponential: flat line
• D. Linear: straight line; Quadratic: W-shape; Exponential: vertical line

Correct answer: A

Rationale: To differentiate between the three types of graphs - scatterplots, a linear graph will display a straight line, a quadratic graph will have a U-shape, and an exponential graph will show a rapid rise or fall in one direction. Choice B is incorrect because linear graphs are represented by straight lines, not curved lines. Choice C is incorrect as linear graphs do not exhibit zigzag patterns, and exponential graphs do not typically result in flat lines. Choice D is incorrect because quadratic graphs form a U-shape, not a W-shape, and exponential graphs do not represent vertical lines.

5. Which type of muscle tissue contracts involuntarily and is found in organs like the heart and intestines?

• A. Skeletal muscle
• B. Cardiac muscle
• C. Smooth muscle
• D. All of the above

Correct answer: C

Rationale: Smooth muscle is the type of muscle tissue that contracts involuntarily and is found in organs like the heart and intestines. Skeletal muscle is responsible for voluntary movements, like those involved in skeletal system actions. Cardiac muscle is found in the heart and contracts involuntarily, but it is distinct from smooth muscle. The heart's muscle is specialized and forms the myocardium, which is not the same as the smooth muscle found in organs like the intestines. Therefore, the correct answer is C) Smooth muscle.
