hey can someone explain why E is not correct? E seems to be correct as the progressive system because of its flaws takes less as tax compared to that from the poorest one. So then a flat tax rate would give the poor a fair chance compared to the progressive system

Looks like its important to apply knowledge of the context here.

why do we need fewer? why not few since there is no comparison being made.

So C is my answer.

For people who have never worked for a living, any job may instill a valuable sense of self-worth and open doors to better jobs in the future (A) may instill a valuable sense of self-worth and open doors to better jobs in the future - ok (B) might instill for...

The theory of multiple intelligences asserts that there is more than one type of intelligence. Proponents of this model differ on the number of intelligences . Gardner, for example, originally proposed seven, but has since added an eighth. His categories are linguistic, logical-mathematical, musical...

Might be long but this is how I did:

sequence: -1 1 2 1 -1 -2 | -1 1 2 1 -1 -2 | ..... period of 6

so 1000/6 = 166 and rem 4

sum of each period is 0, so sum = sum of last 4 terms i.e -1 1 2 1 = 3

since there are less numbers it can be done without formula

7 XX = 9 - 1 (as 00 can't be since we are asked to find numbers more than 700)
7X7 = 9
77X = 9
-----
27 - 1

similarly for 800 series and 900 series total are 27 and 27

so total = 27*3 - 1 = 80
