1. Select the correct word for the blank in the following sentence: 'The other day, Stan ____ reviewing his class notes in preparation for the final exam.'

• A. begins
• B. begun
• C. begin
• D. began

Correct answer: D

Rationale: The sentence is in the past tense, indicating that the action occurred before the present moment. 'Began' is the correct past tense form of the verb 'begin' in this context. It shows that Stan started reviewing his class notes in the past. Choice A ('begins') is incorrect as it represents present tense. Choice B ('begun') is incorrect as it is the past participle form and does not fit the sentence structure. Choice C ('begin') is incorrect as it is the base form of the verb and not appropriate for the past tense context of the sentence.

2. 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.

3. Which of these molecules contains glucose?

• A. Proteins
• B. Lipids
• C. Nucleic acids
• D. Carbohydrates

Correct answer: D

Rationale: Glucose is a type of simple sugar and is classified as a carbohydrate. It is commonly found in various carbohydrate-containing foods such as fruits, vegetables, grains, and sugary snacks. Therefore, the molecule containing glucose would be a carbohydrate, making choice D the correct answer. Proteins (choice A) are made up of amino acids, lipids (choice B) are fats, and nucleic acids (choice C) are DNA and RNA, none of which contain glucose.

4. She was so mad at her boyfriend, she __________ on him when he called.

• A. Yelled
• B. Screamed
• C. Speak
• D. Hung up

Correct answer: D

Rationale: 'Hung up' is correct because it is the proper phrasal verb used when referring to ending a phone call. In this context, the sentence implies that the woman ended the call abruptly due to being angry. 'Yelled' and 'Screamed' both suggest vocalizing loudly, which doesn't fit the situation described. 'Speak' is incorrect as it should be 'spoke' for proper verb tense agreement.

5. Select the word in the following sentence that is not used correctly. On departing, the patient complimented her therapist and counselor.

• A. departing
• B. complimented
• C. therapist
• D. counselor

Correct answer: C

Rationale: The word 'therapist' in the sentence is used correctly. However, the word 'councilor' is misspelled and should be 'counselor' to refer to a mental health professional providing therapy services. The correct term should have an 's' after 'counselor,' making it 'counselor' instead of 'councilor.' Therefore, the word 'councilor' is the one not used correctly in the sentence.
