Question

i dont yet know the ______ number of cookies i need to bake for tomorrows party—i wont know the correct number until i learn how many people are coming.
a. alert
b. ancient
c. exact
d. invisible
e. im not sure

Explanation:

The sentence is about not knowing the precise number of cookies needed. "Exact" means precise or accurate, which fits the context (needing to know the correct number based on attendees). "Alert" (aware), "ancient" (old), and "invisible" (unseen) do not relate to the number of cookies. So "exact" is the correct choice.

Answer:

c. exact
