1. A clinic sees an average of 25 patients every 4 hours. If the clinic is open for 8 hours, how many patients will they see in total?

A. 35
B. 50
C. 75
D. 200

Correct answer: D

Rationale: Rationale: 1. First, determine how many patients the clinic sees in one hour: 25 patients / 4 hours = 6.25 patients per hour (approximately 6 patients per hour) 2. Since the clinic is open for 8 hours, multiply the number of patients seen per hour by the number of hours the clinic is open: 6.25 patients/hour * 8 hours = 50 patients 3. Therefore, the clinic will see a total of 50 patients in 8 hours, which corresponds to answer choice D) 200.

2. Identify the correct sentence structure.

A. The cat sleeping on the mat
B. The cat is sleeping on the mat
C. The mat that the cat is sleeping on
D. Sleeping on the mat is the cat

Correct answer: B

Rationale: The correct sentence structure is 'The cat is sleeping on the mat.' This is a complete and grammatically correct sentence following a standard subject-verb-object structure. 'The cat' is the subject, 'is sleeping' is the verb, and 'on the mat' is the prepositional phrase describing where the action is taking place. Choices A, C, and D are incorrect. Option A is a sentence fragment lacking a verb; option C is a dependent clause lacking a main clause, and option D has a subject-verb inversion making it awkward and incorrect.

3. Where is the ovary located in a flowering plant?

A. Anther
B. Pistil
C. Stamen
D. Calyx

Correct answer: B

Rationale: The ovary is located in the pistil of a flowering plant. The pistil is the female reproductive part of the flower, and it consists of the ovary, style, and stigma. The ovary contains ovules, which develop into seeds after fertilization. Choice A, 'Anther,' is incorrect because the anther is the part of the flower's stamen that produces pollen. Choice C, 'Stamen,' is incorrect because the stamen is the male reproductive part of the flower, consisting of the anther and filament. Choice D, 'Calyx,' is incorrect because the calyx is the outermost whorl of a flower, composed of sepals that protect the flower bud.

4. The development of the disease was 'insidious'. What does insidious mean in this context?

A. Gradual
B. Momentous
C. Sudden
D. Innocuous

Correct answer: A

Rationale: In this context, 'insidious' means progressing slowly but having harmful effects. This matches the meaning of 'gradual,' making it the correct answer. 'Momentous' means significant or important, which is not the meaning conveyed by 'insidious.' 'Sudden' means abrupt or unexpected, opposite to the slow progression indicated by 'insidious.' 'Innocuous' means harmless, which is the opposite of the harmful effects associated with an insidious disease.

5. The new mother wanted to use cloth diapers rather than disposables.

A. Close
B. Clothing
C. Cloth
D. Clothes

Correct answer: C

Rationale: The correct choice is C. Cloth because in the sentence, the new mother expressed a preference for using cloth diapers over disposables. 'Cloth' refers to a type of diaper material, and it makes sense in the context of the sentence. Choice A, 'Close,' is incorrect as it does not relate to the type of diapers being discussed. Choice B, 'Clothing,' is incorrect as it refers to garments worn on the body, not diapers. Choice D, 'Clothes,' is also incorrect as it is used for general garments, not specific to diapers.
