Correct Answer: D

Rationale: Option D correctly spells the words 'discipline' and 'perseverance.' The correct spelling of these words is crucial for effective communication and clarity in writing. In options A, B, and C, there are misspellings of 'discipline' and 'perseverance,' which can lead to confusion and impact the overall quality of the writing. Thus, option D is the correct choice as it accurately represents the correct spelling of both words.

Correct Answer: C

Rationale: The complete subject in the sentence is 'All of Shannon's family and friends.' This phrase encompasses the entirety of the group involved in celebrating Shannon's 50th birthday at Caf© Sorrento. It includes both her family and friends collectively, highlighting the full extent of individuals who participated in the celebration. The term 'All of Shannon's family and friends' is essential for providing a comprehensive subject that covers everyone who contributed to making the event special. Choices A, B, and D are incorrect because they do not capture the complete scope of individuals involved in the birthday celebration, unlike choice C which encompasses both Shannon's family and friends.

Correct Answer: C

Rationale: The correct answer is 'But.' In this sentence, the conjunction 'but' is used to show a contrast between the usual routine of taking a walk after breakfast and the fact that it was raining today. 'While' suggests a concurrent action, 'Because' implies causation, and 'When' introduces a time relationship, none of which are suitable in this context.

Correct Answer: B

Rationale: The correct usage of 'affect' in a sentence is as a verb meaning to influence something, as in 'The weather will affect our plans.' Choice A is incorrect because 'affect' should be 'effect,' which is a noun representing the result of an action. Choice C is incorrect as 'affect' should be 'effect' to describe a disorder. Choice D is incorrect because 'affect' should be 'effect' to convey the result of the news.

Correct Answer: A

Rationale: The prefix circum- means 'around' or 'surrounding.' In words like circumference (the distance around a circle), circumnavigate (to travel around something), and circumstance (the conditions surrounding an event), the prefix implies the idea of being around or encompassing. Choices B, C, and D are incorrect because the words do not primarily relate to travel, size, or area; instead, they share the common theme of being around or surrounding something.
