18. In modern life you will end up with more and better choices if you A. focus on what you do best and then trade with others for what they do best. B. make sure that you are equally skilled at doing everything.

## Step 1<br />This problem is a multiple-choice question that tests your understanding of the concept of specialization and trade in economics. The question asks which of the two options would lead to more and better choices in modern life.<br /><br />## Step 2<br />Option A suggests focusing on what you do best and then trading with others for what they do best. This is a principle of specialization and trade, which is a fundamental concept in economics. Specialization allows individuals or countries to focus on producing goods or services they are most efficient at, and then trade with others who are efficient at producing different goods or services. This leads to more efficient use of resources and increased overall production.<br /><br />## Step 3<br />Option B suggests making sure that you are equally skilled at doing everything. This is not a practical or efficient approach in economics. If everyone were equally skilled at everything, there would be no need for specialization or trade. This would lead to less efficient use of resources and decreased overall production.
