Question

Richard saw 16 clients on a busy Friday. Every single client appeared to be in perfect health, showing no signs of any disease. Although Richard is always careful, he is much more so when clients obviously appear to be sick. On Monday, Richard came down with a bad cold. If it is TRUE that he caught this cold from one of the clients he saw on Friday, what else must also be true?

a) Richard was already getting sick on Friday.

b) The client from whom Richard acquired his cold was not contagious.

c) The client from whom Richard acquired his cold was asymptomatic.

d) Richard never washed his hands on Friday.

Answer 1

If Richard caught his cold from one of the clients he saw on Friday, the client must have been asymptomatic.

Step-by-step explanation:

If it is true that Richard caught his cold from one of the clients he saw on Friday, the following must also be true:

c) The client from whom Richard acquired his cold was asymptomatic.

The fact that all the clients Richard saw on Friday appeared to be in perfect health and showed no signs of any disease indicates that they were asymptomatic. If Richard caught his cold from one of them, it means that the client was carrying the virus but did not show any symptoms.

It is important to note that the other options (a, b, and d) cannot be inferred from the information provided. We cannot conclude whether Richard was already getting sick on Friday, whether the client from whom he acquired the cold was contagious, or whether Richard did not wash his hands on Friday.
