Correct Answer: A

Rationale: The correct answer is A: "intra-". The prefix "intra-" is used to indicate that something is inside or within. For example, "intracellular" means within a cell, and "intrapersonal" means within oneself. Choice B, "trans-", typically indicates across, beyond, or through, not inside or within. Choice C, "anti-", is used to indicate against or opposed to. Choice D, "hyper-", usually denotes excessive or above normal levels, not inside or within.

Correct Answer: B

Rationale: The correct answer is B. In this phrase, the words 'Senator' and 'California' are capitalized correctly since they refer to a specific position and a proper noun, respectively. 'Senator' is capitalized as it is part of the title and 'California' is capitalized as a proper noun. Choice A is incorrect because 'President' should be capitalized when it precedes a specific name, like 'President Carter.' Choice C is incorrect because 'Aunt' and 'Uncle' are not proper nouns and should not be capitalized. Choice D is incorrect because only 'New Year's Eve' should be capitalized as it is a proper noun for the event.

Correct Answer: B

Rationale: The correct punctuation in this case is to use a comma (,) to set off the nonrestrictive clause 'whose death shocked America in April of 2016.' This clause provides additional information about the artist Prince without changing the essential meaning of the sentence. Choice A has a semicolon (;) which is incorrect as it separates two closely related independent clauses. Choice C uses em dashes (-) which are incorrect as they should be used for emphasis or to set off information. Choice D uses a colon (:) which is incorrect as it introduces a list or an explanation, not additional information about the artist Prince. Therefore, the correctly punctuated sentence is: 'The artist Prince, whose death shocked America in April of 2016, was one of the most successful musical artists of the last century.'

Correct Answer: D

Rationale: The correct plural form of 'potato' is 'potatoes.' In English, most plural nouns form by adding '-es' or simply '-s' to the singular form. Therefore, 'potatoes' is the correctly formed plural noun in this list. The other choices, 'vertebrae,' 'geese,' and 'octopuses,' are the correct plural forms of 'vertebra,' 'goose,' and 'octopus,' respectively. They demonstrate the common rule of adding '-es' or '-s' to form plural nouns.

Correct Answer: B

Rationale: The misspelled word in the sentence is 'astronemers,' which should be spelled as 'astronomers.' 'Astrophysicists,' 'techniques,' and 'technology' are all correctly spelled words in the sentence. Ensuring proper spelling is essential for effective communication and clarity. The term 'astronomers' refers to individuals who study celestial bodies, including stars, making it the correct answer in this context.
