How is Bill related to Betty?(1) Cindy, the wife of Bills only brother...
Given: Bill and Betty's relationship needs to be determined.

(1) Cindy, the wife of Bill's only brother Chris does not have any siblings.

(2) Betty is Cindy's brother-in-law's wife.

To determine Bill's relationship with Betty, we need to understand the family tree and the relationships between the various individuals.

(1) Statement (1) alone is not sufficient to answer the question as it only provides information about Cindy and her siblings, but does not provide any information about Betty or her relationship with Bill.

(2) Statement (2) alone is not sufficient to answer the question as it only provides information about Betty's relationship with Cindy's brother-in-law and does not provide any direct information about Bill's relationship with Betty.

(1) + (2) Together:

By combining both the statements, we can determine the family tree and relationships between the individuals as follows:

- Bill has only one brother, Chris.
- Chris is married to Cindy.
- Cindy does not have any siblings.
- Betty is the wife of Cindy's brother-in-law.
- Therefore, Betty is related to Cindy through her marriage to Cindy's brother-in-law, who is Chris (Bill's brother).

Hence, we can conclude that Bill and Betty are related through their respective spouses, i.e., Betty is related to Bill through her marriage to Chris, who is Bill's only brother.

Therefore, both statements (1) and (2) together are sufficient to answer the question, but neither statement alone is sufficient. The correct answer is option (c).

How is Bill related to Betty?(1) Cindy, the wife of Bills only brother...
Evaluate Statement (1) ALONE
Statement 1: Cindy, the wife of Bill's only brother Chris does not have any siblings.
We know that Cindy has no siblings and she is the wife of Bill's only brother Chris. So, this statement has helped us establish the relation between Cindy and Bill. However, this statement does not provide any information about Betty and is hence not sufficient to answer the question.
Statement 1 ALONE is NOT sufficient.
Eliminate choices A and D. Choices narrow down to B, C, or E.
Evaluate Statement (2) ALONE
Statement 2: Betty is Cindy's brother in law's wife.

We know that Betty is Cindy's brother in law's wife. This statement establishes a relation between Cindy and Betty. This does not answer the question of how Bill is related to either Cindy or Betty.
Statement 2 ALONE is not sufficient. Eliminate choice B.
Evaluate the statements together
Statement 1: Cindy, the wife of Bill's only brother Chris does not have any siblings.
Statement 2: Betty is Cindy's brother in law's wife.

We combine the two statements, we know that Bill and Cindy are related to each other through Chris, who is the only brother of Bill and that Cindy is Betty's brother in law's wife.
Cindy does not have any siblings and hence her brother in law has to necessarily be her husband's sibling. As Chris is the only brother of Bill, Cindy's brother in law has to be Bill and Betty is his wife.
Statements TOGETHER are sufficient.
Choice C is the answer.
