1. What is the energy required to remove the outermost electron from an atom called?

• A. covalent bonding
• B. electronegativity
• C. atomic radius
• D. ionization energy

Correct answer: D

Rationale: Ionization energy is the energy needed to remove the outermost electron from an atom, resulting in the formation of a positively charged ion. The higher the ionization energy, the more difficult it is to extract an electron. Electronegativity, however, measures an atom's ability to attract shared electrons in a chemical bond. Atomic radius refers to the distance from the nucleus to the outermost electron. Covalent bonding involves sharing electron pairs between atoms to create a stable bond. Therefore, the correct answer is ionization energy as it specifically relates to the energy needed to remove an electron from an atom.

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. What is another word for elated?

• A. Edified
• B. Confused
• C. Flabbergasted
• D. Delighted

Correct answer: D

Rationale: The word 'elated' means to be ecstatically happy or joyful. Similarly, 'delighted' also means to be extremely pleased or filled with joy. Therefore, 'delighted' is another word that could be used to express the same meaning as 'elated.' Choices A, B, and C are incorrect. 'Edified' means to instruct or enlighten, 'confused' means to be unclear or bewildered, and 'flabbergasted' means to be astonished or amazed, which do not convey the same meaning as 'elated.'

4. Select the word that makes this sentence grammatically correct. Our subcommittee ___________ on the fourth Wednesday of each month.

• A. meet
• B. meets
• C. meeting
• D. are meeting

Correct answer: B

Rationale: The word 'subcommittee' is singular, so the correct verb to use is 'meets' as it agrees with the singular subject. 'Meets' is the present tense form of the verb that matches a singular subject. Choice A 'meet' is incorrect as it is the plural form of the verb. Choice C 'meeting' is a gerund and does not fit the sentence structure. Choice D 'are meeting' is incorrect as 'are' is not the correct auxiliary verb to pair with 'subcommittee'.

5. 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.
