Which sentence best summarizes the result of the experiment in this excerpt?
A Playing card games increases the spread of colds.
B Colds can only affect people who touch their faces.
C Colds can infect people in many different ways.
D Gloves are the only way to prevent colds.
The correct answer is C Colds can infect people in many different ways.
Explanation: This summary captures the broader scope of the experiment’s results by indicating that colds can spread through various methods, rather than limiting the spread to playing cards, face touching, or the use of gloves. It addresses the multifactorial nature of cold transmission.
The best answer is C Colds can infect people in many different ways.
Explanation: This option summarizes the broader concept that the experiment likely explored various ways colds are transmitted, rather than suggesting a single method or cause. The other options either narrow the focus too much or imply limitations that are not supported by the general findings of experiments on cold transmission.
