TEAS 7 English Practice Test
1. Which of the answer choices best explains the purpose of the parentheses in the sentence?
- A. To offer brief commentary on the subject matter being discussed
- B. To modify or qualify the statement that came immediately before
- C. To identify information that was located using another source
- D. To set off useful information that does not fit the flow of the sentence
Correct answer: D
Rationale: The correct answer is D. Parentheses are used to set off supplementary information (the years of Franz Joseph I's reign) that provides context but does not disrupt the flow of the main sentence. Choice A is incorrect as the purpose of the parentheses in this case is not to offer commentary but to provide additional information. Choice B is incorrect as the parentheses do not modify or qualify the statement before. Choice C is incorrect as the information in the parentheses is not identified as being from another source.
2. Fill in the blanks in the following sentence: Enzymes are ________ molecules that serve as _______ for certain biological reactions.
- A. complex; suppressors
- B. acidic; triggers
- C. small; targets
- D. large; catalysts
Correct answer: D
Rationale: Enzymes are large molecules that act as catalysts, accelerating chemical reactions by lowering the activation energy required for the reactions to occur. In the context of biological reactions, enzymes function as catalysts, not suppressors, triggers, or targets. The use of 'large' and 'catalysts' accurately describes the nature and role of enzymes in facilitating biological processes.
3. Which word has the same root as 'unscathed'?
- A. category
- B. scar
- C. scratch
- D. category
Correct answer: C
Rationale: The word 'unscathed' means without harm or damage. The word 'scratch' shares the same root related to physical marks or damage, making it the correct choice. 'Category' and 'scar' do not have the same root as 'unscathed' and are not related to the concept of being unharmed, making them incorrect choices.
4. If a patient had a heart attack and tissue in the left ventricle lost blood flow, what would you most expect to happen?
- A. Blood would not flow from the lungs.
- B. Blood would back up in the legs.
- C. Blood would not be pumped to the body.
- D. Blood would not be oxygenated.
Correct answer: C
Rationale: The correct answer is C: 'Blood would not be pumped to the body.' When tissue in the left ventricle loses blood flow due to a heart attack, the ability of the left ventricle to pump oxygenated blood to the body is compromised. This can lead to serious consequences for the patient's overall health and organ function. Choices A, B, and D are incorrect because a heart attack affecting the left ventricle does not directly impact blood flow from the lungs, cause blood to back up in the legs, or prevent blood from being oxygenated. The primary concern is the compromised ability of the left ventricle to pump blood to the rest of the body, affecting overall circulation and organ perfusion.
5. Which of the following reagents can be used to convert a primary alcohol to an alkyl halide?
- A. HI
- B. H2O
- C. NaOH
- D. SOCl2
Correct answer: D
Rationale: SOCl2 (thionyl chloride) is commonly used to convert primary alcohols to alkyl halides through an SN2 mechanism. Thionyl chloride reacts with the alcohol to form an alkyl chloride. HI (hydroiodic acid) is typically used to convert alcohols to alkyl iodides specifically, not alkyl halides in general. H2O (water) and NaOH (sodium hydroxide) are not reagents used for converting alcohols to alkyl halides. Therefore, the correct answer is SOCl2 as it facilitates the conversion of primary alcohols to alkyl halides, unlike the other options provided.
