1. In a city with a population of 51,623, 9.5% of the population voted for a new proposition. How many people approximately voted?

• A. 3,000 people
• B. 5,000 people
• C. 7,000 people
• D. 10,000 people

Correct answer: B

Rationale: To find the number of people who voted, you need to calculate 9.5% of the total population of 51,623. 9.5% of 51,623 is approximately 0.095 x 51,623 = 4,999.85, which is rounded to approximately 5,000 people. Therefore, the correct answer is 5,000 people. Choice A, 3,000 people, is incorrect as it is lower than the calculated value. Choice C, 7,000 people, is incorrect as it is higher than the calculated value. Choice D, 10,000 people, is incorrect as it is much higher than the calculated value.

2. What term describes a series of muscle contractions that transports food down the digestive tract in a wave-like fashion?

• A. digestion
• B. deglutition
• C. defecation
• D. peristalsis

Correct answer: D

Rationale: Peristalsis is the correct term for the series of muscle contractions that move food down the digestive tract in a wave-like manner. This process helps propel food through the esophagus, stomach, and intestines, facilitating digestion and nutrient absorption. Digestion (Choice A) refers to the breakdown of food into smaller components, deglutition (Choice B) is the act of swallowing, and defecation (Choice C) is the elimination of waste from the body. Therefore, peristalsis is the most appropriate term to describe the described muscle contractions in the digestive system.

3. When a car brakes to a stop, friction between the tires and the road acts as:

• A. A balanced force
• B. An unbalanced force causing deceleration
• C. An unbalanced force causing the car to remain at rest
• D. No force at all

Correct answer: B

Rationale: When a car brakes to a stop, friction between the tires and the road acts as an unbalanced force causing deceleration. This friction force opposes the motion of the car, resulting in a decrease in speed until the car comes to a complete stop. Choice A is incorrect because if the forces were balanced, the car would not experience any deceleration. Choice C is incorrect because if the force were unbalanced in the direction of motion, the car would continue to move instead of coming to a stop. Choice D is incorrect because friction between the tires and the road does exert a force, causing deceleration.

4. What is essential for an experiment to be considered successful?

• A. a reasonable hypothesis
• B. a well-written lab report
• C. data that others can reproduce
• D. computer-aided statistical analysis

Correct answer: C

Rationale: For an experiment to be considered successful, it is essential that the data collected and results obtained can be reproduced or replicated by others. This reproducibility ensures the reliability and validity of the experiment's findings. It allows for independent verification of the results and contributes to the overall scientific rigor of the study. While having a reasonable hypothesis, a well-written lab report, and computer-aided statistical analysis are important aspects of an experiment, the ability to reproduce the data is crucial for establishing the experiment's credibility and success. Without reproducibility, the findings may not be reliable, and the experiment's outcomes cannot be verified independently, leading to doubts about its validity.

5. In the sentence, 'The receptionist explained that we would be the next to see the doctor,' which of the following is the complete predicate?

• A. explained that we would be the next to see the doctor
• B. next to see the doctor
• C. explained that we would be next
• D. see the doctor

Correct answer: A

Rationale: The complete predicate is 'explained that we would be the next to see the doctor.' In a sentence, the complete predicate includes the main verb (explained) and all the words that complete its meaning (that we would be the next to see the doctor). Choices B, C, and D do not constitute the complete predicate as they do not include the main verb 'explained' and all associated words that complete its meaning.
