Question

to prepare for careers in international development, some graduates are taking a three - pronged approach: studying data science and econometrics, fields that are relevant to impact assessment; learning a foreign language, which can be essential for certain positions abroad; and taking courses in public policy and administration. choose 1 answer: a no change b studying data science and econometrics, fields that are relevant to impact assessment; c studying data science and econometrics, fields that are relevant to impact assessment: d studying data science and econometrics; fields that are relevant to impact assessment,

Explanation:

The original sentence uses a colon to introduce a list of the three - pronged approach. The part "studying data science and econometrics, fields that are relevant to impact assessment" is the first item in the list. A semicolon is not appropriate here as it is used to separate items in a list when the items themselves contain commas, and a colon is the correct punctuation to introduce the list. So the original version (NO CHANGE) is correct.

Answer:

A. NO CHANGE
