which of the following situations could best be used to illustrate the meaning of signals?
a. wendy closes the book and turns off the light so her sister can get some sleep.
b. maria saw the directors nod and gave the thumbs-up to ben to raise the curtain.
c. alan praises the team for their strong performance in the second half of the game.
d. sara goes through her vocabulary words one more time as she prepares for the test.

Explanation:

A "signal" is an action, gesture, or sound that conveys a specific message to others. Option B involves a non-verbal gesture (the director's nod) that acts as a signal to trigger a response (Maria signaling Ben to raise the curtain), which directly illustrates the meaning of a signal as a communicative cue. The other options do not involve a deliberate, communicative cue to prompt a specific action.

Answer:

B. Maria saw the director's nod and gave the thumbs-up to Ben to raise the curtain.
