ATI TEAS English and Language Usage

1. Identify the preposition in the following sentence: It's really hot in that room.

A. It
B. hot
C. in
D. that

Correct answer: C

Rationale: The correct answer is "C: in." A preposition is a word that shows the relationship of a noun or pronoun to another word in the sentence. In this sentence, 'in' is the preposition, indicating the location of the heat relative to the room. Choices A, B, and D are not prepositions. 'It' is a pronoun, 'hot' is an adjective, and 'that' is a demonstrative pronoun in this context, not a preposition.

2. Which of the following is NOT a component of the genitourinary system?

A. The kidneys
B. The urethra
C. The rectum
D. The bladder

Correct answer: C

Rationale: The rectum is part of the digestive system, not the genitourinary system. The genitourinary system comprises organs involved in reproduction and urine formation and excretion, such as the kidneys, urethra, and bladder. Choices A, B, and D are all components of the genitourinary system. The kidneys filter blood and produce urine, the urethra is a tube that carries urine from the bladder out of the body, and the bladder stores urine before it is excreted.

3. Which word completes the sentence 'He was ____ by the unexpected turn of events.'?

A. elated (joyful)
B. bewildered (confused)
C. vindicated (justified)
D. apathetic (uninterested)

Correct answer: B

Rationale: In the sentence, 'He was bewildered by the unexpected turn of events,' the word 'bewildered' means confused, which is the most suitable choice to convey the feeling caused by unexpected events. 'Elated' means joyful, 'vindicated' means justified, and 'apathetic' means uninterested, making them less fitting in the context of being surprised or thrown off by unexpected events.

4. Which of the following examples from the paragraph about the Silk Road is a transition sentence?

A. The Silk Road got its name from Chinese silk, which was a major item traded along the route.
B. However, there were many other important trade items, some of which would end up changing the world forever.
C. Because the Silk Road was not just one single road, historians also use the term 'Silk Routes' to describe the network.
D. The Silk Road was an ancient network of trade routes that stretched from China through India all the way to Africa, Greece, Rome, and Great Britain.

Correct answer: B

Rationale: Choice B is the correct answer because it serves as a transition sentence in the paragraph about the Silk Road. It shifts the focus from Chinese silk being a major trade item to the introduction of other important trade items that had a significant impact on the world. This transition indicates a change in the topic being discussed within the paragraph. Choices A, C, and D do not serve as transition sentences. Choice A simply introduces the origin of the Silk Road's name, choice C provides additional information about the network without transitioning to a new topic, and choice D gives a general description of the Silk Road without transitioning to a different aspect of the trade routes.

5. What is the general formula for an alkyl halide?

A. CₙH₂ₙ
B. CₙH₂ₙ₊₂
C. CₙH₂ₙ₊₁X
D. CₙH₂ₙO

Correct answer: C

Rationale: The correct answer is option C, 'CₙH₂ₙ₊₁X.' This is the general formula for an alkyl halide, where X represents a halogen atom (such as fluorine, chlorine, bromine, or iodine), and the hydrocarbon chain is represented by CₙH₂ₙ₊₁. Option A, 'CₙH₂ₙ,' is incorrect because it does not account for the presence of a halogen atom. Option B, 'CₙH₂ₙ₊₂,' is incorrect as it represents an alkene, not an alkyl halide. Option D, 'CₙH₂ₙO,' is also incorrect as it suggests the presence of oxygen, which is not characteristic of alkyl halides.
