2. In the Martian parliament, deputies from three parties are in session: "Vowels," "Consonants," and "Sibilants" - 50 deputies from each party. A bill "On the Reconstruction of Martian Canals" was put to a vote. After the vote, 30 deputies from each party said they voted "for," 10 said they voted against, and the rest said they abstained. It is known that among the "consonant" deputies, those who supported the bill were the only ones who told the truth, among the "vowel" deputies - those who voted against, and among the "sibilant" deputies - those who abstained. The bill is considered adopted if at least $50 \%$ of the votes are in favor. Was the bill adopted?
Answer: No. Solution: Those from the "vowels" or "sibilants" who voted "for" were lying, meaning they answered that they voted "against" or abstained. In both parties, 20 people answered this way. Even if all those who answered this way voted "for," it would be no more than 40 people. Those from the "consonants" who voted "for" were telling the truth, meaning they answered that they voted "for." In the "Consonants" party, 30 people answered this way. Even if all those who answered this way voted "for," it would be no more than 30 people. Therefore, in total, across the three parties, no more than 70 people voted "for." And 50% of the votes is 75 people. Therefore, the proposal did not pass.
