Correct Answer: consequences

Solution : The first option is correct.

Consequences refer to the results or effects that follow a particular action or decision. In the sentence, it suggests that when people wish for things, they may not consider the potential outcomes or repercussions of those wishes.

The meanings of the other options are:

• A fraction is a mathematical expression representing a part of a whole.
• Copiousness refers to the state of being abundant, ample, or overflowing with something.
• Hazards are a potential source of danger or risk.

Therefore, the correct sentence is: " Sometimes we wish for things, but we do not think about their consequences."
