1. Which of the following is a characteristic of alkenes?

• A. They have a double bond between carbon atoms.
• B. They are saturated hydrocarbons.
• C. They contain only single bonds.
• D. They are derivatives of ammonia.

Correct answer: A

Rationale: Alkenes are hydrocarbons that contain at least one carbon-carbon double bond. This double bond is a key characteristic that distinguishes alkenes from other types of hydrocarbons. Option A correctly identifies this defining feature of alkenes, making it the correct answer. Choices B, C, and D are incorrect. Choice B is incorrect because alkenes are unsaturated hydrocarbons due to the presence of double bonds. Choice C is incorrect as alkenes do not contain only single bonds; they have at least one double bond. Choice D is incorrect because alkenes are not derivatives of ammonia; they are a distinct class of organic compounds with carbon-carbon double bonds.

2. What can the reader infer from this passage?

• A. The children tortured Gulliver.
• B. Gulliver traveled because he wanted to meet new people.
• C. Gulliver is considerably larger than the children who are playing around him.
• D. Gulliver has a genuine love and enthusiasm for people of all sizes.

Correct answer: C

Rationale: The correct answer is C. In the passage, it is mentioned that the children play in Gulliver's hair, implying that he is considerably larger than them. This suggests that Gulliver is of a significant size compared to the children. Choice A is incorrect as there is no indication of the children torturing Gulliver in the passage. Choice B is incorrect because the passage does not mention Gulliver's reason for traveling. Choice D is incorrect as the passage does not provide evidence of Gulliver's love and enthusiasm for people of all sizes.

3. Which nervous system controls voluntary motor movement?

• A. Parasympathetic
• B. Sympathetic
• C. Autonomic
• D. Somatic

Correct answer: D

Rationale: The correct answer is D: Somatic. The somatic nervous system is responsible for controlling voluntary motor movements. It includes the motor neurons that innervate skeletal muscles and allows us to consciously control our movements. The parasympathetic and sympathetic nervous systems are part of the autonomic nervous system, which controls involuntary functions such as heart rate and digestion. Therefore, choices A, B, and C are incorrect as they are components of the autonomic nervous system and are not primarily responsible for voluntary motor movements.

4. How many people can participate in a volleyball game?

• A. 14
• B. 15
• C. half of a class
• D. an entire class

Correct answer: D

Rationale: Based on the extract provided, a volleyball game can involve an entire class participating. The passage mentions that with just one net and one ball, an entire class can play volleyball. While the number of participants in a volleyball game can vary, the specific reference to a whole class in the passage indicates that a significant number of people can take part. Therefore, the correct answer is 'an entire class.' Choice A, '14,' is incorrect because the passage explicitly mentions that an entire class can participate, which typically involves more than 14 individuals. Choice B, '15,' is incorrect as it does not account for the flexibility of the number of participants in a volleyball game as stated in the passage. Choice C, 'half of a class,' is incorrect as the passage clearly states that an entire class can participate, not just half.

5. A farmer plans to install fencing around a certain field. If each side of the hexagonal field is 320 feet long, and fencing costs $75 per foot, how much will the farmer need to spend on fencing material to enclose the perimeter of the field?

• A. $2,240
• B. $2,800
• C. $3,360
• D. $4,480

Correct answer: C

Rationale: The field is a hexagon with six equal sides, each 320 feet long. To find the total cost of fencing material needed, multiply the cost per foot ($75) by the total perimeter of the field (6 sides x 320 feet). Therefore, the total cost will be $75 x 6 x 320 = $3,360. Thus, the farmer will need to spend $3,360 on fencing material. Choice A, $2,240, is incorrect as it does not account for the total perimeter of the field. Choice B, $2,800, is incorrect as it underestimates the total cost by not considering all sides of the hexagon. Choice D, $4,480, is incorrect as it overestimates the total cost by multiplying incorrectly or considering extra sides.
