Read the paragraph.Laughter is a message we send to other people. Most people rarely laugh when they are alone. Laughter helps us interact with others. "The first laughter appears at about 3.5 to 4 months of age, long before we’re able to speak” (Provine). Babies, who cannot speak, use laughter to relate to their mothers, and their mothers, who can speak, use laughter rather than words to relate back.
Answer
A
Communication Is Key
B
Communication Is Bonding
C
Laughter: A Way to Communicate
D
Laughter: The Way Babies Communicate
Explanation
The paragraph explains that laughter sends a message and helps people interact, including babies and their mothers. “Laughter: A Way to Communicate” best captures this main idea. Choice D is too narrow because the paragraph discusses communication between people generally, not only how babies communicate.
