When conducting scientific research, any information that is found must be analyzed to determine its validity. Joel is a firm believer that exposure to cold weather can cause the common cold. He conducts online research about this topic. Of the excerpts below, which would be considered biased?

AThe flu and the common cold are caused by viruses.
BViruses are passed by contact between people.
CCold and flu season occurs when the weather is cold, so there must be a connection.
DAll of the above excerpts are biased.

Verified Answer :

The answer is c. Cold and flu season occurs when the weather is cold, so there must be a connection.

Even though choices a. and b. could make sense, nothing in Joel's research implies the connection between the choices and cold. Therefore, this leaves choice c. as the right one. If cold and flu season occurs
 when the weather is cold, there must be a connection between cold and cold weather.

Answer: C. Cold and flu season occurs when the weather is cold, so there must be a connection.
