1. Select the phrase that makes the following sentence grammatically correct: I hope that my parents ___________ if I am able to graduate early.

• A. are delighted
• B. were delighted
• C. will be delighted
• D. will have been delighted

Correct answer: C

Rationale: The correct answer is C: 'will be delighted.' In this context, the sentence is expressing a future possibility of graduating early, so the phrase 'will be delighted' in the future tense is the most appropriate choice to match the context. Choices A, B, and D are incorrect because they do not convey the future tense needed in this sentence. Choice A ('are delighted') is in the present tense, choice B ('were delighted') is in the past tense, and choice D ('will have been delighted') uses a more complex future perfect tense which is not necessary in this context.

2. When a crane hoists a massive object at a constant velocity compared to lifting the same object gradually, the work done by the crane is:

• A. Less
• B. More
• C. Identical
• D. Dependent on the object's mass

Correct answer: C

Rationale: The work done by the crane is identical in both scenarios. Work is defined as the force applied over a distance. Since the force needed to lift the object is equal to its weight and the displacement is the same, the work done is identical, whether the object is lifted gradually or at a constant velocity. Choice A is incorrect because the work done is the same in both cases. Choice B is incorrect as well since the work done does not increase. Choice D is incorrect as the mass of the object does not affect the work done by the crane in this scenario.

3. What is the correct formula for sodium nitrate?

• A. NaNO
• B. Na NO
• C. NaNO₃
• D. Na NO₂

Correct answer: C

Rationale: The correct formula for sodium nitrate is NaNO₃. In this formula, 'Na' represents sodium, 'N' represents nitrogen, and 'O₃' represents three oxygen atoms. Sodium nitrate consists of one sodium ion (Na⁺) and one nitrate ion (NO₃⁻), which means the correct formula is NaNO₃. Choice A (NaNO) is incorrect as it lacks the subscript indicating the presence of three oxygen atoms. Choice B (Na NO) is incorrect as it includes a space between 'Na' and 'NO', which is not part of the standard chemical formula notation. Choice D (Na NO₂) is incorrect as it indicates a different compound with a nitrite ion (NO₂⁻) instead of nitrate ion.

4. What is the process of cell division that results in two daughter cells with identical genetic material?

• A. Mitosis
• B. Meiosis
• C. Binary Fission
• D. Budding

Correct answer: A

Rationale: The correct answer is A, Mitosis. Mitosis is the process of cell division in which a cell divides and produces two daughter cells that are genetically identical to the parent cell. Choice B, Meiosis, is a type of cell division that produces gametes with half the number of chromosomes. Choice C, Binary Fission, is a form of asexual reproduction in single-celled organisms. Choice D, Budding, is a form of asexual reproduction where a new organism develops from an outgrowth or bud on the parent.

5. Which of the following sentences uses the correct form of the verb?

• A. She was going to the store
• B. She was going to the store
• C. She has gone to the store
• D. She gone to the store

Correct answer: B

Rationale: The correct answer is 'She was going to the store.' This sentence uses the correct form of the past continuous tense, which is appropriate for describing an action in progress in the past. Choice A is the only option that uses the correct verb form. Choice C uses the present perfect tense, which is not suitable for describing a past action in progress. Choice D is incorrect as it lacks the auxiliary verb 'has' in the sentence structure.
