ATI TEAS 7

TEAS Reading Practice Test

1. Which statement best details the central idea in this passage?

A. It discusses insects that transition from water to air during their life cycle.
B. It explores the field of entomology, particularly focusing on gills.
C. It explains the mechanism of insects' respiration.
D. It encourages readers to contribute to insect conservation efforts.

Correct answer: A

Rationale: The correct answer is A because the passage primarily discusses certain insects that spend time in water during their early stages and then transition to an aerial life when they reach adulthood. It highlights how these insects, such as Stoneflies, May-flies, and Dragon-flies, live in water initially and then in the air during their adult stage. This central idea is best captured by choice A. <br> Choice B is incorrect because while the passage mentions gills as a part of the respiratory system of aquatic insects, it does not delve into entomology as a field. Choice C is incorrect as it does not solely focus on defining insect respiration but rather on the transition of certain insects between aquatic and aerial environments. Choice D is incorrect as the passage does not explicitly invite readers to participate in insect preservation efforts; it mainly focuses on describing the life cycle of specific insects.

2. Which sentence uses the present perfect continuous tense correctly?

A. I have been working on this project since morning.
B. She has finished the book already.
C. They will be leaving for vacation tomorrow.
D. He had been living in the city for ten years.

Correct answer: A

Rationale: Option A, 'I have been working on this project since morning,' uses the present perfect continuous tense correctly. This structure implies an action that started in the past (working on the project) and is still ongoing up to the present moment. Choice B is incorrect as it uses the present perfect tense ('has finished'), which indicates a completed action with relevance to the present. Choice C uses the future continuous tense ('will be leaving'), and Choice D uses the past perfect continuous tense ('had been living'). Therefore, only Choice A fits the criteria for the present perfect continuous tense.

3. What is the equivalent of 0.3 mg in mcg?

A. 300 mcg
B. 30 mcg
C. 3000 mcg
D. 3 mcg

Correct answer: A

Rationale: To convert milligrams (mg) to micrograms (mcg), you need to multiply by 1000 since 1 mg is equal to 1000 mcg. Therefore, 0.3 mg x 1000 = 300 mcg. This conversion is crucial in healthcare to ensure accurate medication dosages. Choice B (30 mcg) is incorrect as it represents the conversion of 0.03 mg to mcg. Choice C (3000 mcg) is incorrect as it is the result of multiplying 0.3 mg by 10 instead of 1000. Choice D (3 mcg) is incorrect as it is the result of not multiplying by 1000 to convert milligrams to micrograms.

4. Identify the interrogative sentence in the following options:

A. The delicious pie disappeared quickly.
B. What is your favorite color?
C. Please open the window.
D. He ran as fast as he could.

Correct answer: B

Rationale: An interrogative sentence is a type of sentence that asks a question. In this case, choice B 'What is your favorite color?' is an interrogative sentence because it is asking a question and ends with a question mark. Choices A, C, and D are not interrogative sentences as they do not pose a question to elicit a response. Choice A is a declarative sentence, choice C is an imperative sentence, and choice D is also a declarative sentence.

5. Which phrase best completes the definition of a memoir?

A. A historical account of a person's life written by one who has intimate knowledge of the person's life
B. A historical account of a person's life written by the person himself or herself
C. A fictional account about a famous person
D. A nonfictional account about a famous person without factual reference

Correct answer: A

Rationale: A memoir is a historical account of a person's life written by someone who has intimate knowledge of that person's life, not necessarily by the person themselves. This distinguishes it from an autobiography, which is written by the person themselves. Memoirs are nonfictional and based on factual references, making option A the most fitting completion of the definition. Choices B, C, and D are incorrect because a memoir is not necessarily written by the person about whom it is written, it is not fictional, and it should be based on factual references to be considered a memoir.
