Question

to prepare for careers in international development, some graduates are taking a three - pronged approach: ______ learning a foreign language, which can be essential for certain positions abroad; and taking courses in public policy and administration. which choice completes the text so that it conforms to the conventions of standard english? choose 1 answer: a studying data science and econometrics; fields that are relevant to impact assessment; 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:

To determine the correct answer, we analyze the punctuation and sentence structure. The original sentence uses a colon to introduce a list of three items (the three - pronged approach). The items in the list should be separated by semicolons, but within each item, we need to use appropriate punctuation for additional information.

• Option A: The semicolon after "econometrics" is incorrect because "fields that are relevant to impact assessment" is a non - restrictive clause providing more information about "data science and econometrics", and a semicolon here would incorrectly split the clause from its antecedent.
• Option B: Here, a comma is used to introduce the non - restrictive clause "fields that are relevant to impact assessment" which correctly modifies "data science and econometrics". Also, the overall structure fits the list format (the three items: studying data science and econometrics..., learning a foreign language..., taking courses...).
• Option C: The colon at the end is incorrect as it does not fit the context of the list. The list items should end with a semicolon (to separate the three items) or a period, but a colon is not appropriate here.
• Option D: The semicolon after "econometrics" is wrong for the same reason as in Option A, and the comma at the end does not fit the structure of the list.

Answer:

B. studying data science and econometrics, fields that are relevant to impact assessment;
