In a large residential building, there is a rule that no pets are allowed. A group of pet lovers tried to change that rule but failed. The rule-changing procedure outlined in the building’s regulations states that only if a group of tenants can obtain the signatures of 10 percent of the tenants on a petition to change a rule will the proposed change be put to a majority vote of all the tenants in the building. It follows that the pet lovers were voted down on their proposal by the majority of the tenants.

The argument depends on which one of the following assumptions?

(A) The pet lovers succeeded in obtaining the signatures of 10 percent of the tenants on their petition.

(B) The signatures of less than 10 percent of the tenants were obtained on the pet lovers’ petition.

(C) Ninety percent of the tenants are against changing the rule forbidding pets.

(D) The support of 10 percent of the tenants for a rule change ensures that the rule change will be adopted.

(E) The failure of the pet lovers to obtain the signatures of 10 percent of the tenants on their petition for a rule change ensures that the rule change will be voted down by a majority of the tenants.

The argument talks about a residential building where the procedure to change a rule
is to first obtain the signatures of 10 percent of the tenants on a petition to change a
rule and later get a majority vote of all the tenants in the building.

Option A(The pet lovers succeeded in obtaining the signatures of 10 percent of the
tenants on their petition)
is an assumption which is necessary for the argument to
hold good because if the tenants did not get the 10% of signatures, the majority vote also
wouldn't have happened!

The core is: only goes to majority vote if obtains 10 percent of tenants' signatures --> must have gone to majority vote and been voted down

The assumption here is that the petition had 10% of tenants' signatures. If it DIDN'T, the conclusion doesn't work at all; it would not have gone to majority vote. This is (A).

(B) states the opposite of (A). If this is true, the argument doesn't work. They needed to have obtained ten percent.

(C) is incorrect because they needed to obtain 10 percent, but certainly could have obtained more. If they got more signatures, it wouldn't be true that 90% is against the petition.

(D) is not in there at all. We're talking about 10% of signatures on a petition and getting to majority vote. The rule in the stimulus was voted down.

(E) if we don't have 10% then it will be voted down by majority? No, this is not in there.

The argument depends on which one of the following assumptions?

(A) The pet lovers succeeded in obtaining the signatures of 10 percent of the tenants on their petition. -Correct. Directly referable from the passage

(B) The signatures of less than 10 percent of the tenants were obtained on the pet lovers’ petition. -Can't be true since a voting happened

(C) Ninety percent of the tenants are against changing the rule forbidding pets. -Majority doesn't mean 90%; it can be 51%.

(D) The support of 10 percent of the tenants for a rule change ensures that the rule change will be adopted. -Extreme

(E) The failure of the pet lovers to obtain the signatures of 10 percent of the tenants on their petition for a rule change ensures that the rule change will be voted down by a majority of the tenants. -Out of scope
