1. My mother and _____ went shopping for clothes yesterday.

• A. me
• B. I
• C. myself
• D. mine

Correct answer: B

Rationale: The correct answer is 'I'. In this sentence, 'I' is the subject pronoun that should be used to complete the sentence correctly. 'Me' is an object pronoun, 'myself' is a reflexive pronoun, and 'mine' is a possessive pronoun, none of which are suitable in this context.

2. Which vitamin is essential for the clotting of blood?

• A. Vitamin A
• B. Vitamin K
• C. Vitamin C
• D. Vitamin D

Correct answer: B

Rationale: Vitamin K is essential for the synthesis of proteins required for blood clotting. It specifically assists in the activation of clotting factors to prevent excessive bleeding from injuries. Vitamin K plays a crucial role in maintaining a balance between clotting and bleeding in the body. Choices A, C, and D are incorrect. Vitamin A is important for vision, immune function, and skin health. Vitamin C is essential for collagen synthesis and acts as an antioxidant. Vitamin D is crucial for calcium absorption and bone health.

3. He tried to remember the names of all the people who were there that night.

• A. that
• B. who
• C. which
• D. whom

Correct answer: B

Rationale: In this context, 'who' is the correct relative pronoun to refer to people. 'That' is used for things, 'which' is used for animals or things, and 'whom' is an object pronoun, not needed in this sentence. Therefore, 'who' is the most appropriate choice.

4. What is the correct formula for calcium carbonate?

• A. CaSO₃
• B. CaCO₃
• C. Ca(OH)₂
• D. CH₃OH

Correct answer: B

Rationale: The correct formula for calcium carbonate is CaCO₃, which consists of one calcium (Ca) atom, one carbon (C) atom, and three oxygen (O) atoms. Therefore, choice B, CaCO₃, is the accurate formula for calcium carbonate. Choices A, C, and D do not represent the correct formula for calcium carbonate. Choice A, CaSO₃, is calcium sulfite, not calcium carbonate. Choice C, Ca(OH)₂, is calcium hydroxide, and choice D, CH₃OH, is methanol, none of which are correct formulas for calcium carbonate.

5. How many milliliters are in 4 liters?

• A. 40 milliliters
• B. 40 milliliters
• C. 4000 milliliters
• D. 4 milliliters

Correct answer: C

Rationale: To convert liters to milliliters, you must remember that 1 liter is equal to 1,000 milliliters. Therefore, to find out how many milliliters are in 4 liters, you multiply 4 by 1,000. This gives you a total of 4,000 milliliters in 4 liters. Choices A, B, and D are incorrect because they do not correctly convert liters to milliliters. A and B incorrectly represent 40 milliliters, which would be the result if you mistakenly multiplied by 10 instead of 1,000. Choice D is even further from the correct answer, as it suggests only 4 milliliters, which is significantly less than the actual conversion of 4 liters to milliliters.
