Question

role means :

a slow longitudinal movement or deformation

normal or customary activity of a person in a social setting

an event in which something is displaced without rotation

something that may increase or decrease

Explanation:

To determine the meaning of "role", we analyze each option:

• The first option describes a type of movement/deformation, not related to "role".
• The second option: A "role" refers to the normal or customary activity a person has in a social setting (e.g., a teacher's role in a school).
• The third option describes a displacement event, not related to "role".
• The fourth option refers to something variable, not related to "role".

Answer:

B. normal or customary activity of a person in a social setting (assuming the second option is labeled B; if the original labels were different, adjust the identifier but keep the text. Since the options are presented with radio buttons, and the second one is the correct definition of "role", we identify it as the second option with its text.)
