Correct Answer: D

Rationale: The word 'prefer' should be changed to 'prefers' to match the singular subject 'Louis.' The correct sentence should be: 'Fredericka always orders pancakes, but Louis prefers waffles.' Choice A 'always,' Choice B 'orders,' and Choice C 'but' are used correctly in the sentence and do not need any corrections.

Correct Answer: B

Rationale: The word 'more' is the correct choice to make the sentence grammatically correct. 'More' is used to indicate an increase in quantity, which fits well in the sentence structure 'I added more pepper to the casserole.' Choices A, C, and D are incorrect. 'Too' implies an excessive amount, 'those' refers to specific items, and 'many' is used for countable objects, none of which are suitable in this context.

Correct Answer: C

Rationale: The correct answer is 'will be certified' because it correctly indicates the future tense of the action of certifying the students after they pass the exam. This phrase accurately conveys the timing of the certification process in relation to the completion of the exam. Choice A 'being certified' is incorrect as it does not specify the future tense, while choice B 'have been certified' is incorrect as it indicates a past action. Choice D 'are certifying' is incorrect as it suggests the certification is currently happening, which is not the intended meaning in the sentence.

Correct Answer: C

Rationale: The correct punctuation needed in the sentence is a colon. A colon is used to introduce a list or an explanation. In this case, the colon helps to indicate that the following phrase ('Remember the old saying') is providing an explanation or clarification related to the phrase before it. Choice A, the exclamation point, is incorrect as the sentence is not expressing strong emotion or excitement. Choice B, the apostrophe, is incorrect as it is not needed for possession or contraction. Choice D, the semicolon, is incorrect as it is used to connect two independent clauses, which is not the case here.

Correct Answer: C

Rationale: The correct answer is 'C: receive.' In this sentence, 'receive' is the infinitive form of the verb that should follow the preposition 'to.' Therefore, the sentence should read: 'Sadie and her mother were excited to receive the award.' 'Be received' (A) is not appropriate in this context as it changes the passive voice. 'Receiving' (B) is a gerund form and does not fit after 'to.' 'Have been received' (D) is in the wrong tense and does not suit the sentence structure.
