Which word is used incorrectly in the following sentence? If you calculate too quickly, you may possibly fail to get the right answer.

Correct Answer: B

Rationale: The word 'quickly' is used incorrectly in the sentence. The correct word that should be used here is 'speedily.' 'Quickly' is an adverb that describes the speed at which an action is performed. However, in this context, the sentence needs an adverb that conveys doing something in a hurried or rushed manner, which is 'speedily.' Therefore, the sentence should read as: 'If you calculate too speedily, you may possibly fail to get the right answer.' The other choices ('calculate,' 'possibly,' 'right') are used appropriately in the sentence and do not need to be changed.

Correct Answer: A

Rationale: The correct preposition to use in this sentence is 'with.' The sentence should read: 'Do not be afraid to consult with your peers.' In this context, 'with' is the appropriate preposition to indicate collaborating or seeking advice from your peers. The other prepositions ('from,' 'by,' 'in') do not convey the intended meaning of seeking advice or collaborating with your peers in this context.

Correct Answer: A

Rationale: The correct sentence is 'Because she was uncertain of her abilities, Renee asked for help.' This sentence uses a comma after the introductory phrase 'Because she was uncertain of her abilities' to set it off from the main clause 'Renee asked for help.' The comma helps to separate the two parts of the sentence clearly and indicates the pause that should be there when reading it aloud. Options B, C, and D are incorrect because they either use a semicolon incorrectly or have commas placed incorrectly within the sentence.

Correct Answer: C

Rationale: In this sentence, 'Three days from now' indicates a future timeframe, so the correct verb tense to use is the future tense. The phrase 'will perform in a show' is the best choice to make the sentence grammatically correct because it aligns with the future action of the horses. Choice A ('performing in a show') uses the present participle and is incorrect in this context. Choice B ('performed in a show') uses the past tense, which is not suitable for a future event. Choice D ('have performed in a show') uses the present perfect tense, which is also not appropriate for a future action. Therefore, the correct answer is C.

Correct Answer: A

Rationale: The word 'iterate' is not spelled correctly in the sentence. The correct word that should be used here is 'itinerant,' which means constantly traveling from place to place, especially for work. In this context, 'iterate' does not fit as it means to repeat a process or utterance. 'Continually' is spelled correctly and means happening without interruption. 'Within' and 'district' are also spelled correctly and are used appropriately in the sentence. Therefore, choice A is the correct answer.
