Question 7

Retail sales in the U.S. have consistently increased.

This statement requires a citation because it presents a specific claim about retail sales trends that can be verified through data and research. Providing a citation supports the credibility of the claim and allows readers to access the original data sources.

A) Most of the author's friends enjoy avocado toast.

This statement does not require a citation as it reflects a personal observation or anecdote. Personal experiences or opinions do not need external verification, making this option incorrect in the context of needing a citation.

B) Avocados are delicious.

This statement is subjective and represents a personal opinion. Since it does not convey factual information that can be cited, it does not require a citation, thus making it an incorrect choice.

D) They can be found at your local grocer's.

This statement is a general observation that does not need a citation. It describes the availability of avocados in common grocery stores, which is widely accepted knowledge and does not require validation through a source.

Conclusion

The need for a citation is essential for statements that present factual claims, such as the assertion about retail sales in the U.S. being on the rise. Options A, B, and D are based on personal experience or general knowledge and do not necessitate a citation, while option C clearly states a factual trend that should be supported by external data. Therefore, option C is definitively the correct answer.
