Question

In the following argument, identify either the extra claims, or express the implied claim.

Answer 1

In my opinion, the implied claim here is "You had better take an umbrella with you." It is a claim that can be inferred from the first claim about the barometer showing the pressure. An implied claim doesn't have to be explicitly said. It comes as a conclusion to the premise. When your mother tells you about the weather forecast while you are preparing to leave, she usually implies that you should dress accordingly.

Answer 2

Since the barometer is falling, the extra claim in the statement is that a falling barometer indicates that rain will be in the immediate forecast. Stating that you should bring an umbrella with you suggest the falling barometer implies rain.
