PLZZ HELPP WILL GIVE BRANLYEST(IF CORRECT) What must an author include to convince readers that a claim is true? photographs
some kind of evidence

quotes and evidence

(if you need just one then do quotes)

Explanation:

This kind of feels like an "all of the above"

But my closest one is "some kind of evidence"

the answer to the question is punishment. or more specifically, positive punishment.

positive punishment occurs when a behavior is given a negative consequence for the individual doing the behavior.

sara no longer wants to ask questions (the behavior) because she is ridiculed by mr. smith (the punishment).

reinforcement is inaccurate because reinforcement always gives positive consequences for the individual doing the behavior, be it by introducing a pleasant consequence or removing an unpleasant one.
