Acountry with a high dependency ratio might have many i. children ii. elderly people iii. women iv. non-farmers

Option I and II

Explanation:

In population demographics, the dependency ratio is the number of the people who depend on the active class to take care of them.

The active class consist of roughly people aged between 16 - 65 years.

The dependent class is from 0 - 15 and 66 and above. The former are too young to earn a living, whilst the later are old and retired.

Both groups are dependent on the active population. A population that has a high proportion of these people (0- 14 years) and ( 66 and above) has a high dependence ratio.

Hence options I and II

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.
