1. Select the word or phrase that makes the following sentence grammatically correct: I was extremely surprised ___________ of her dismissal from the staff.

• A. learning
• B. to learn
• C. of learning
• D. have learned

Correct answer: B

Rationale: The correct phrase to use with 'surprised' in this sentence is 'to learn.' In this context, 'to learn' functions as an infinitive to indicate the purpose or reason for the surprise. 'Learning' (Choice A) is incorrect as it doesn't serve as an infinitive in this sentence. 'Of learning' (Choice C) is incorrect as it doesn't provide the correct structure needed in the sentence. 'Have learned' (Choice D) is incorrect because the verb tense does not match the context of the sentence.

2. Identify the dependent clause in this sentence: The mother dog left her bed as soon as the puppies were asleep.

• A. As soon as the puppies were asleep
• B. Left her bed as soon as
• C. The puppies were asleep
• D. The mother dog left her bed

Correct answer: A

Rationale: The correct answer is A: 'As soon as the puppies were asleep' is the dependent clause in the sentence. It functions as an adverbial clause, indicating a time relationship with the action of the mother dog leaving her bed. Dependent clauses rely on independent clauses to form complete sentences and cannot stand alone. Choice B is incorrect because it separates the dependent clause. Choice C is incorrect as it is a noun phrase. Choice D is incorrect as it is an independent clause.

3. A chemist takes 100 mL of a 40 g NaCl solution and dilutes it to 1L. What is the concentration (molarity) of the new solution?

• A. 0.04 M NaCl
• B. 0.25 M NaCl
• C. 0.40 M NaCl
• D. 2.5 M NaCl

Correct answer: C

Rationale: Initially, the chemist has 40 g of NaCl in 100 mL of solution. To find the initial molarity, we need to calculate the number of moles of NaCl using the molar mass of NaCl (58.44 g/mol). After dilution to 1 L, the molarity of the new solution can be calculated by dividing the moles of NaCl by the total volume in liters. Therefore, the concentration (molarity) of the new solution is 0.40 M NaCl. Choice A (0.04 M NaCl) is incorrect because it doesn't consider the correct molar concentration after dilution. Choice B (0.25 M NaCl) is incorrect as it also doesn't account for the correct molar concentration post-dilution. Choice D (2.5 M NaCl) is incorrect as it is too concentrated given the initial amount of NaCl and the dilution factor.

4. Which part of the brain is responsible for memory and learning?

• A. Frontal lobe
• B. Temporal lobe
• C. Parietal lobe
• D. Occipital lobe

Correct answer: B

Rationale: The correct answer is B: Temporal lobe. The temporal lobe of the brain plays a crucial role in processing auditory information, memory formation, and learning. It contains the hippocampus, a structure vital for the formation of new memories and the conversion of short-term memories into long-term ones. Damage to the temporal lobe can lead to memory impairments and difficulties in learning new information. Choices A, C, and D are incorrect because the frontal lobe is primarily involved in decision making, problem-solving, and emotional control; the parietal lobe is responsible for sensory processing and spatial orientation; and the occipital lobe is mainly dedicated to visual processing and interpretation.

5. Which sentence correctly uses a colon?

• A. She had one goal: to win the race.
• B. He needs milk, eggs, and bread.
• C. The meeting is at 3 PM.
• D. She bought milk, eggs, bread.

Correct answer: A

Rationale: The correct answer is A: 'She had one goal: to win the race.' This sentence uses a colon to introduce the purpose or explanation that follows. It is a grammatically correct use of a colon. Choice B is incorrect as the colon is not needed after 'needs'; a list of items follows, which does not require a colon. Choice C is a simple statement of time and does not require a colon. Choice D is also incorrect since a colon is not suitable after 'bought'; the items bought are listed without the need for a colon.
