ESL/EFL Test #99 "a, some or any", answer 1

We need a kilo of apples.

Correct answer: (a) a

we need some kilo of apples

To use the adjective some meaning several/a few with a countable noun like kilo, you need a plural form. You could therefore say: We need some kilos of apples (but not some kilo), although a few kilos is more commonly used.
