1. Select the word or phrase that makes the following sentence grammatically correct. After ___________ for an entire afternoon, the resident felt revitalized.

• A. having rest
• B. resting
• C. rested
• D. rest

Correct answer: B

Rationale: The correct answer is 'B - resting' because it is the present participle form of the verb 'rest' and fits appropriately in the sentence structure 'After resting for an entire afternoon, the resident felt revitalized.' The present participle is used to show an ongoing action that happened before the feeling of revitalization. Choice A 'having rest' is incorrect as it does not convey the continuous action needed in this context. Choice C 'rested' is incorrect as it is the past tense form and does not match the tense of the sentence. Choice D 'rest' is incorrect as it is the base form of the verb and does not provide the needed -ing form for the sentence.

2. What does intact mean?

• A. Damaged
• B. In place, unharmed
• C. Destroyed
• D. Incomplete

Correct answer: B

Rationale: The correct answer is B: 'In place, unharmed.' 'Intact' refers to something that is whole, undamaged, or unharmed. Choices A, C, and D are incorrect because they describe states opposite to what intact means. 'Damaged,' 'Destroyed,' and 'Incomplete' all signify a lack of wholeness or harm, which is contrary to the meaning of intact.

3. Which part of a plant’s reproductive system is of a different “gender” than the others?

• A. Stamen
• B. Pistil
• C. Stigma
• D. Style

Correct answer: A

Rationale: The stamen is the male reproductive organ of a plant, producing pollen grains. The pistil, consisting of the stigma, style, and ovary, is the female reproductive organ. Therefore, the stamen is of a different 'gender' than the other parts of the plant's reproductive system. The pistil, stigma, and style are all part of the female reproductive system, involved in receiving pollen and supporting fertilization. Stamen is the correct answer as it is the male part of a plant's reproductive system, making it different 'gender-wise' from the female parts.

4. How does asexual reproduction differ from sexual reproduction?

• A. asexual reproduction results in all cells being identical to the original cell; sexual reproduction results in half of the cells being identical to the original cell
• B. asexual reproduction results in two cells that contribute genetic material to daughter cells, resulting in significantly greater variation
• C. sexual reproduction involves two cells that contribute genetic material to daughter cells, resulting in significantly greater variation
• D. sexual reproduction involves one cell that yields all cells produced to be identical

Correct answer: C

Rationale: Sexual reproduction involves two cells (gametes) that contribute genetic material to daughter cells, resulting in significantly greater genetic variation in the offspring. This genetic variation is essential for evolution and adaptation to environmental changes. In contrast, asexual reproduction involves one cell dividing to produce offspring that are genetically identical to the parent cell. Choice A is incorrect because sexual reproduction does not result in half of the cells being identical to the original cell; it involves two cells contributing genetic material. Choice B is incorrect because asexual reproduction does not result in significantly greater variation; it produces genetically identical offspring. Choice D is incorrect because sexual reproduction involves two cells contributing genetic material, not one cell yielding all identical cells.

5. A teacher's aide is preparing a snack for the class. In order to prepare the powdered drink, the aide must convert the directions to metric. The directions say, 'Dilute contents of package in 2 quarts of water.' The aide has a measuring device marked in liters. How many liters of water should be used?

• A. 2
• B. 1
• C. 3 liters
• D. 5 liters

Correct answer: A

Rationale: To convert 2 quarts to liters, we can use the conversion factor that 1 quart is approximately equal to 0.95 liters. Therefore, 2 quarts would be approximately 1.9 liters, which is closest to 2 liters. As the measuring device is marked in liters, the teacher's aide should use 2 liters of water to dilute the contents of the package. Choice A is correct. Choice B is incorrect because it's the same as the original amount in quarts. Choice C is incorrect as it suggests using more water than necessary. Choice D is incorrect as it suggests using significantly more water than necessary.
