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: D

Rationale: The correct answer is 'Our.' In this sentence, the possessive pronoun 'Our' is needed to show ownership and make the sentence grammatically correct. 'Screaming our took the shopkeeper by surprise' indicates that the shopkeeper was surprised by the screaming of a group or individuals related to 'our.' Choices A, B, and C are incorrect as they are pronouns referring to people ('We', 'They', 'Them'), not possessive pronouns that indicate ownership.

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: A

Rationale: The correct answer is 'him or her' because it agrees with the singular noun 'child.' When referring to a singular subject of unknown gender, 'him or her' is a suitable pronoun choice to maintain grammatical correctness. Options B, C, and D are incorrect as they do not match the singular form of 'child.' Using 'them' (B) would be plural, 'it' (C) is not appropriate for a person, and 'she or he' (D) is unnecessarily wordy and less commonly used in modern English.

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.
