1. What is the function of an adjective in a sentence?

• A. To describe a verb
• B. To connect clauses
• C. To describe a noun
• D. To show action

Correct answer: C

Rationale: The function of an adjective in a sentence is to describe or modify a noun. Adjectives provide more information about the noun they modify, such as its size, color, shape, etc. For example, in the sentence 'The tall building,' 'tall' is an adjective describing the noun 'building.' Choices A, B, and D are incorrect. Adjectives do not describe verbs (adverbs do that), connect clauses (conjunctions do that), or show action (verbs do that).

2. What is kwashiorkor, a protein deficiency disease, characterized by?

• A. Muscle wasting
• B. Night blindness
• C. Scurvy
• D. Rickets

Correct answer: A

Rationale: Kwashiorkor is a severe acute malnutrition condition resulting from insufficient dietary protein intake. It is characterized by symptoms such as edema, skin lesions, an enlarged liver with fatty infiltrates, and notably, muscle wasting. Muscle wasting occurs as the body breaks down muscle tissue to obtain essential amino acids for vital functions. Night blindness (option B) is associated with vitamin A deficiency, scurvy (option C) results from a lack of vitamin C, and rickets (option D) is caused by a deficiency in vitamin D, calcium, or phosphate.

3. What is the difference between a pure substance and a mixture?

• A. Pure substances have a fixed composition, mixtures don't.
• B. Mixtures have a fixed composition, pure substances don't.
• C. Pure substances can be in any state, mixtures are not always solids.
• D. Pure substances are always elements, mixtures are always compounds.

Correct answer: A

Rationale: Pure substances have a definite and constant composition, meaning they are made up of only one type of atom or molecule with fixed proportions. This composition does not vary. On the other hand, mixtures are composed of two or more substances physically combined. The components of a mixture can be present in varying proportions, leading to a variable composition. Choice A is correct as it accurately distinguishes between pure substances and mixtures based on the fixed composition of pure substances and the variable composition of mixtures. Choice B is incorrect because mixtures, not pure substances, have variable compositions. Choice C is incorrect as both pure substances and mixtures can exist in different states. Choice D is incorrect because pure substances can be compounds as well, not exclusively elements, and mixtures can contain elements and compounds.

4. What is the process of converting light energy into chemical energy called?

• A. Respiration
• B. Fermentation
• C. Photosynthesis
• D. Hydrolysis

Correct answer: C

Rationale: - Respiration (Option A) is the process by which cells break down glucose to release energy. - Fermentation (Option B) is an anaerobic process that also involves the breakdown of glucose to release energy. - Hydrolysis (Option D) is a chemical process that involves the breakdown of molecules by adding water. Photosynthesis (Option C) is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. During photosynthesis, plants use sunlight, carbon dioxide, and water to produce glucose and oxygen. This process is essential for the survival of plants and ultimately sustains life on Earth by providing oxygen for other organisms to breathe and serving as a source of energy in the food chain.

5. Which of the following is the correct tense used in the bold part in this sentence? My grandpa WILL BE WRITING a memoir...

• A. Future progressive
• B. Past perfect
• C. Future simple
• D. Present perfective

Correct answer: A

Rationale: The correct answer is A, Future progressive. 'Will be writing' indicates an ongoing action that will occur in the future, which is the future progressive tense. Choice B, Past perfect, is incorrect as it refers to an action completed before a specified time in the past. Choice C, Future simple, is incorrect as it refers to a simple future action without indicating ongoing progress. Choice D, Present perfective, is incorrect as it does not match the tense used in the sentence.
