有很多個選項只寫一個還是可以寫很多個 - 英檢

大家好, 看機經時看到這題:

When you make a purchase, which of the following will affect your decision?
1. Suggestions from friends
2. Media (advertisements from TV, magazines)
3. Recommendations from salesperson
4. On your own

其實我會先考慮(1)朋友的建議, 再(4)自己做決定.
可是題幹說"which of the following",
這是代表說我只能選一個寫嗎?

謝謝!
