Complete the dramatic botanist's journal entry about her disastrous jungle expedition by choosing the correct phrase for each blank.

We spent much of the expedition walking in circles. We quickly realized that few of our maps were actually accurate for this region. Because of the endless rain, very little of the original equipment survived the trek. Our guide finally confessed that all of us were hopelessly lost.

much of the is used because "expedition" is singular, referring to a single block of time/event. "Many" would require a plural noun.

few of our is used because "maps" is a plural countable noun preceded by a possessive determiner ("our").

little of the is used because "equipment" is an uncountable noun. We need "of" because it is followed by the determiner "the".

all of us is the correct structure before an object pronoun. "All us" is non-standard, and "every of us" is grammatically incorrect.
