Astudent is writing a research paper about drunk driving in the united states. which piece of information is objective?
the punishment for drunk driving is not strict enough, and lawmakers need to pass tougher laws.
more than one million people were arrested for driving drunk in the united states last year.
people who drive drunk are selfish, and they do not care about the people they hurt.
there should be more educational programs to teach people about the dangers of drunk driving

Let's go throught the options:

The punishment for drunk driving is not strict enough, and lawmakers need to pass tougher laws.
- this is not objective, the boldfaced parts contain opinions and judgements.

More than one million people were arrested for driving drunk in the United States last year.
- this is objective! no judgements or opinions.

People who drive drunk are selfish, and they do not care about the people they hurt.

-not objective! "selfish" is a very judgmental word

There should be more educational programs to teach people about the dangers of drunk driving
- this is also not objective, the boldfaced parts show the subjective  part! 

The definition of objective is 'not influenced by opinions,' so the answer would be "More than one million people were arrested for drunk driving in the United States last year."
