Mashika -
if Ms. Puerta’s supporters also support Mr. Quintana, then no segment that supports Mr. Quintana can also support Mr. Ramirez.
Salim-
This directly contradicts Mashika’s conditional statement if the premise about Ms. Puerta’s supporters also supporting Mr. Quintana were true.
Inference -
Since Salim’s statement is factual (based on conclusive polling data), Mashika’s conditional claim must be false.
The only way Mashika’s statement is false is if Ms. Puerta’s supporters do not significantly support Mr. Quintana.
Thus, it must be true that at least one segment supports Ms. Puerta but not Mr. Quintana.
Answer Choices -
(A) At least one segment of the electorate provides significant support neither to Mr. Quintana nor to Mr. Ramirez.
Not necessarily true. The argument doesn’t say anything about segments that support neither candidate.
(B) At least one segment of the electorate provides significant support to Ms. Puerta but not to Mr. Quintana.
Correct. This is what we inferred: for Mashika’s conditional claim to be false, there must be at least one segment that supports Ms. Puerta but does not support Mr. Quintana.
(C) Each segment of the electorate provides significant support to Ms. Puerta.
Too strong. The passage only says some segments support Ms. Puerta, not all.
(D) Each segment of the electorate provides significant support to Mr. Quintana.
Too strong. The passage never claims that every segment supports Mr. Quintana.
(E) Each segment of the electorate provides significant support to Mr. Ramirez.
Too strong. The passage only mentions one segment supporting both Quintana and Ramirez, not all.
