Abolish taxes, and real taxpayers would find that their disposable incomes have increased. Abolish taxes, and public employees would find that their incomes have disappeared.

Which one of the following is a logical conclusion that depends on information in both of the statements above?

(A) Public offices should be abolished so that disposable incomes will rise.

(B) The only real taxpayers are those who would have more to spend if they did not pay taxes.

(C) Public employees are not real taxpayers.

(D) Public employees’ incomes should not be taxed since they come from taxes.

(E) If there were no taxes, then public employees could not be paid.

E is very close but the question is very tricky, so take into account this:

It is true that E can be logically derived from the second statement. The issue here is that the question is asking for a logical conclusion that depends on both statements. E only depends on the second statement and the first does not provide any informations relevant to conclude E

C on the other hand is a conclusion that depends on both statements:

(Please excuse my english, these are not formal logic procedures but they provide a general idea)

Lets suppose real tax payers are public employees

Supposition: x is a real tax payer <-> x is a public employee

Taxes are abolished -> y is a real tax payer ^ y has its disposable income increased

Taxes are abolished -> z is a public employee ^ z has its income dessapear

Lets take the person A, A is a real tax payer

Taxes are abolished then:

A is a real tax payer ^ A has its disposable income increased

A is a public employee ^ A has its disposable income increased

But also

A is a public employee ^ A has its income dessapear

So A has its disposable income increased ^ A has its income dessapear

Since we reached a contradiction we conclude that real tax payers cannot be public employees since disposable income cannot increase if the income dissapears.

We reach a contradiction that depend on both statements to proof. Answer E is also right, but it is not what the question is asking, be careful with tricky questions.
