1. What is the purpose of a switch in a circuit?

• A. To reverse the direction of alternating current
• B. To increase the voltage of the battery or cell
• C. To increase the resistance of wires in the circuit
• D. To allow the circuit to open and close

Correct answer: D

Rationale: The purpose of a switch in a circuit is to allow the circuit to open and close. When the switch is turned on, it provides a complete path for the current to flow through the circuit. When the switch is turned off, it breaks the circuit, stopping the flow of current. This function of opening and closing the circuit using a switch is essential for controlling the flow of electricity in various electrical devices and systems. Choices A, B, and C are incorrect because a switch does not reverse the direction of current, increase voltage, or increase resistance in a circuit; its primary function is to open and close the circuit.

2. Why does the author mention 'impact craters' in line 16?

• A. To explain the corrosive effects of atmospheric weathering
• B. To explain why the Moon has no plant life because of meteorites
• C. To show the result of the Moon not having an atmosphere
• D. To show the result of the Moon not having active tectonic or volcanic activity

Correct answer: C

Rationale: The mention of impact craters in the text is to highlight the consequence of the Moon lacking an atmosphere. The absence of an atmosphere on the Moon leaves it vulnerable to meteorite impacts, resulting in the multitude of impact craters on its surface. Choice A is incorrect because the mention of impact craters is not related to atmospheric weathering but rather to the lack of an atmosphere. Choice B is incorrect as it misinterprets the reason for the absence of plant life on the Moon. Choice D is incorrect as the text explicitly states that the Moon lacks tectonic or volcanic activity, which is not the focus of the mention of impact craters.

3. Select the correct word for the blank in the following sentence. The children and ___________ performed a skit for the elderly patients.

• A. he
• B. me
• C. them
• D. her

Correct answer: C

Rationale: In this sentence, we are looking for a pronoun that refers to more than one person. The children and 'them' performed a skit for the elderly patients. 'Them' is the correct pronoun to use in this context to indicate a group of people, which is the plural form of the pronoun. Choice A, 'he,' is singular and would not match the plural subject. Choice B, 'me,' is an object pronoun and does not fit the subject position. Choice D, 'her,' is singular and does not agree with the plural subject 'children and them.' Therefore, the correct answer is 'C: them.'

4. Which organelle contains the genetic material of the cell?

• A. Golgi apparatus
• B. Ribosome
• C. Endoplasmic reticulum
• D. Nucleus

Correct answer: D

Rationale: The correct answer is 'D: Nucleus.' The nucleus is the organelle that contains the cell's genetic material, which is the DNA. The genetic material in the nucleus controls the cell's activities and plays a crucial role in inheritance. Choices A, B, and C are incorrect because the Golgi apparatus is involved in modifying, sorting, and packaging of proteins; ribosomes are involved in protein synthesis; and endoplasmic reticulum is involved in protein and lipid synthesis and transportation, but none of them contain the genetic material of the cell.

5. Which phrase correctly completes the sentence? She went to the party ___ her dislike for the host.

• A. Despite of
• B. Even though
• C. Although
• D. In spite of

Correct answer: D

Rationale: The correct phrase to complete the sentence is 'In spite of.' This phrase is used to indicate that an action is taken despite a particular circumstance or feeling. In this case, she went to the party in spite of her dislike for the host, meaning she attended the party regardless of her negative feelings towards the host. Choice A, 'Despite of,' is incorrect as the correct phrase is 'Despite,' without the preposition 'of.' Choice B, 'Even though,' is not the best fit in this context as it does not express the contrast between attending the party and disliking the host as effectively as 'In spite of.' Choice C, 'Although,' is also not the most suitable choice as it is used to introduce a contrast, but 'In spite of' provides a stronger emphasis on the contradiction between attending the party and disliking the host.
