Select the word or phrase that makes this sentence grammatically correct: 'Picking up groceries ____ one of the things you are supposed to do?'

Correct Answer: A

Rationale: The correct answer is 'Is.' In this sentence, the subject 'picking up groceries' is singular, so it should be followed by the singular form of the verb 'to be,' which is 'is.' The verb should agree with the subject in number. 'Am' is incorrect as it is the first person singular form, 'Is it' creates an unnecessary question structure, and 'Are' is plural, not matching the singular subject. Therefore, 'Is' is needed to make the sentence grammatically correct.

Correct Answer: C

Rationale: The word 'recipe' in the sentence should be 'receipt.' In this context, 'receipt' refers to a proof of payment, whereas 'recipe' is a set of instructions for preparing a dish. Therefore, 'receipt' is the correct word to use in the given sentence. Choice A, 'ringing,' is used correctly as it means the process of totaling the cost of the items. Choice B, 'cashier,' is also used correctly to refer to the person handling the transaction. Choice D, 'change,' is appropriately used to indicate the money returned after payment.

Correct Answer: B

Rationale: The correct word that should replace 'among' in the sentence is 'between' when referring to a distinction between two things. 'Among' is used when referring to more than two items or when the items are part of a group. In this context, 'between' is more appropriate as there are only two treatment protocols being compared.

Correct Answer: D

Rationale: 'Have to' is the correct choice as it fits the sentence structure. The sentence is in the past tense ('did we') and requires the infinitive form 'have to' to express the idea of necessity or obligation in the past. 'Has to' (Choice A) is incorrect as it is present tense, 'haven't' (Choice B) is a negative form and does not make sense in this context, and 'had to' (Choice C) would imply a past obligation that has already been fulfilled, which is not the intended meaning here.

Correct Answer: B

Rationale: 'But' is the conjunction in this sentence. A conjunction is a word that connects clauses or sentences. In this case, 'but' links two contrasting ideas: the little girl wanting a cookie and her decision not to take one. The other options are not conjunctions; 'little' is an adjective, 'take' is a verb, and 'the' is a definite article.

Correct Answer: C

Rationale: In the sentence 'The nurse helped the patient with the medication,' the direct object is 'patient' because it receives the action of being helped. The direct object typically answers the question 'whom' or 'what' after the verb. In this case, 'the patient' is the one being helped by the nurse, making it the direct object. Choices A, B, and D are incorrect. 'Helped' is the verb, 'nurse' is the subject performing the action, and 'medication' is part of a prepositional phrase and does not directly receive the action of the verb.

Correct Answer: A

Rationale: The correct answer is 'Is.' In this sentence, the subject 'picking up groceries' is singular, so it should be followed by the singular form of the verb 'to be,' which is 'is.' The verb should agree with the subject in number. 'Am' is incorrect as it is the first person singular form, 'Is it' creates an unnecessary question structure, and 'Are' is plural, not matching the singular subject. Therefore, 'Is' is needed to make the sentence grammatically correct.

Correct Answer: B

Rationale: 'Badly' is the correct adverb to modify 'danced'. In this context, 'badly' is used to describe the manner in which the student danced, indicating that her dancing performance was not good, contrasting with her singing ability. 'Poorly' (choice C) is also an adverb, but 'badly' is more commonly used in this context to describe performance in an artistic or skill-based activity. Choice D, 'poorer,' is incorrect as it is the comparative form of 'poor,' not the appropriate adverb to describe how she danced.

Correct Answer: C

Rationale: In this sentence, 'us' is the correct pronoun to use. The sentence should read, 'Is the new student coming out to lunch with us?' 'Us' is the objective pronoun that functions as the object of the preposition 'with.' Choice A, 'we,' is incorrect because 'we' is a subject pronoun and does not fit the prepositional phrase 'with us.' Choice B, 'our,' is a possessive pronoun, which is also incorrect in this context. Choice D, 'they,' is a subject pronoun and does not agree with the preposition 'with.' Therefore, the correct answer is 'C: us.'
