Why vocabulary matters in two-part questions
The challenge of two-part questions is not difficulty — it is flexibility. The two questions might ask for completely different types of thinking: reasons in one, evaluation in the other. You need vocabulary that can shift between explaining why something happens and judging whether it is good or bad — sometimes within the same essay.
The patterns and their phrases
Common vocabulary mistakes
"People shop online because it is convenient and cheap. Online shopping saves time. In conclusion, online shopping is very popular."
"The primary reasons are convenience and lower prices. As for whether this is a positive development, I believe the overall impact is beneficial, as it has made goods more accessible."
The most common mistake is spending the entire essay on Question 1 and forgetting Question 2. Use a clear transition phrase to signal you are moving to the second question.
"People shop online for many reasons. Also, online shopping is positive because it is convenient."
"People shop online primarily for convenience and cost. Turning to whether this is positive or negative, I believe the benefits outweigh the drawbacks."
"Also" does not signal a new question — it sounds like you are continuing the same point. Use phrases that explicitly mark the shift: "Turning to," "As for," "Regarding the second question."
"There are many reasons why people shop online: convenience, price, variety, reviews, delivery, and returns. I think it is positive."
"The primary reasons are convenience and lower prices. This shift is largely positive — it has made goods accessible to people in all locations and income brackets, though the decline of physical retail has caused job losses in some communities."
Six reasons in one sentence with a one-sentence evaluation is not balanced. Give equal development to both questions — two well-explained reasons and a well-developed evaluation.
The key phrase in two-part essays is the transition between questions. "Turning to the question of whether this is positive..." tells the examiner you are now addressing Question 2. Without it, they may not realise you have answered both parts. Make the shift visible — do not assume the examiner will figure it out.
