Answer 2

`2,000,000\ pages`

Explanation:

we know that

Each page of a top-secret report on aliens requires
`2` KB of space in digital format

so

by proportion

Find the maximum number of pages for
`4*10^(6)` KB

`(1)/(2)(page)/(KB) =(x)/(4*10^(6))(pages)/(KB)\\ \\x=4*10^(6)/2\\ \\x=2*10^(6)\ pages\\ \\x=2,000,000\ pages`
