Building L is shorter than Building X. Building Y is shorter than Building L, but Building M is shorter than Building Y. therefore, Building is shorter than Building J. What premise must be added to require the conclusion to be true, assuming all of the premises are true?

A.

Building L is taller than J.

B.

Building X is taller than J.

C.

Building J is taller than L.

D.

Building J is taller than M.

Answer and Explanation

The Correct Answer is C

A. Building L is taller than J: This doesn’t directly support the conclusion because it doesn't provide enough information about the height relationship between J and M.

B. Building X is taller than J: This doesn't help either. While it gives us information about the height of Building X relative to J, it doesn't establish the necessary comparison between J and M.

C. Building J is taller than L: This directly helps establish the relationship. If Building J is taller than L, and we know that L is taller than several other buildings (such as Y and M), it follows logically that J is taller than M. Thus, we can conclude that Building J is taller than M, supporting the statement that Building J is indeed shorter than M in the required order.

D. Building J is taller than M: This contradicts the conclusion, so it can’t be correct.

Correct Answer is B

Explanation

A. the horses in the study were racehorses and the findings do not apply to horses in general: The study specifically involved racehorses, so this statement is true, but it doesn’t directly address the core finding of the study, which is the relationship between iron-rich diet and increased track speed.

B. iron rich feed is associated with an increased track speed in racehorses: The study shows that 75% of the horses showed improved track speed after receiving an iron-rich diet, indicating an association between the two variables.

C. regulations regarding the type of dietary intake for racehorses should be enforced: The study doesn’t suggest that regulations are necessary; it only shows an association. The study does not provide enough information to make regulatory recommendations.

D. regular, non-iron enriched feed causes decreased track speed in racehorses: The study does not discuss non-iron-enriched feed or make any claims about its effect on racehorse speed. The study only examined the effects of an iron-rich diet, not the comparison with other types of feed.

Correct Answer is C

Explanation

A. prove statement one conclusively: While the additional statements provide support for the idea presented in statement one, they don't prove it conclusively. They give context and additional information but don't necessarily establish a direct proof.

B. explain why statement one is false: Statement one is not false, so this option is not correct. The other statements provide information that aligns with and supports statement one, not refute it.

C. provide support for statement one: Statements two, three, and four build upon statement one by showing how ancient civilizations used clay to record cultural ideas, honor individuals, and create pottery that gives us much of the knowledge we have about those civilizations.

D. describe all of the uses for clay: While the statements describe some uses for clay, they do not cover all possible uses. They are specifically focused on the cultural and historical significance of clay, not a comprehensive list of all clay's uses.
