Answer:
One thousand. (1000)
Step-by-step explanation:
Approximation is a system of counting to the NEAREST WHOLE.
This 'wholes' could be TENS, HUNDREDS, THOUSANDS, MILLIONS etc.
From the question,
Literally we have "zero thousand" just like saying, zero thousand of people
It makes no sense mathematically, hence, since there are larger figures (up to 60, 100), the most closely rounded up figure to zero would be one.
Hence the answer to the nearest thousand would be 1000
