many/ alot of w pytaniach

zawsze myslalam ze 'a lot of' uzywa sie tylko w positive statrements, od pytan sa much/many tymczasem w testach z tej strony jako poprawne odpowiedzi sa:

I don't have a lot of friends..
Did you take a lot of clothes?
have you got a lot of luggage?

i jak to ma sie do faktu ze a lot of tylko zdaniach twierdzacych???

nijak sie nie ma

taka odpowiedz sobie daruj.
