Knowing the daily weather forecast is most likely to affect which of the following decisions?

A. where to go on vacation

B. what clothes to wear

C. where to buy a house

D. which college to attend

I understand here "daily" to mean a specific day, for example tomorrow. This is most likely to influence what clothes you decide to buy (answer b).

Vacation would be more likely influenced by a weekly forecast and buying a house by a yearly forecast.

College should be chosen for other reasons, not the weather!
