Which of these is an example of a hasty generalization?

a. she's wearing a green shirt, so green must be her favorite color.
b. he's on the ski team, so he knows how to ski.
c. my dog is the best dog ever because he's so good.
d. if you like mayonnaise, you will like anchovies.

A. She's wearing a green shirt, so green must be her favorite color.

Hasty generalizations are conclusions that are not logically justified by sufficient evidence.  In this case, you answer would be A, "she's wearing a green shirt, so green must be her favorite color". You can't assume that someone's favourite colour is green because one day he woke up and decided to wear a green shirt. Perhaps that one was the only clean shirt the person had.

You could not say that B is hasty generalization because for someone to be on the ski team they should know how to ski, so there is little evidence to think that. In C, the person talking about his dog knows him/her so, despite the fact that he does not know all the dogs in the world, he can talk about his.  Finally, sometimes mayonnaise is made with anchovies so it is kind of logical to think that if you like mayonnaise, you will like anchovies.

c is a symbol. when bernice gets her hair cut, it is the authors way of showing the affects and demands of pier pressure and the over-all attitudes of people at the time.

the legal limit for the drivers who can drive after consuming any amount of alcohol is 21 years.

explanation:

on november 1, 1996, a "zero tolerance law" was put into effect in the new york state.

according to this zero tolerance law, for people under the age of 21 years, it was illegal to purchase and possess alcohol or to drive after consuming any amount of it.

also, the alcohol involvement rate for the drivers under the age of 21 was roughly twice that of elderly drivers.
