Question

In the 2020 summer Olympics' Javelin throw finals, Neeraj Chopra exhibited a spectacular performance to win the gold medal. The silver medal was won by Jakub Vadlejch and the bronze medal was won by Vitezlav Vesely. There were six rounds of throws with each athlete having one throw per round. The best of all the throws of each athlete is considered for the medal. Following were the observations about the throws:
(i) The first and second rounds were dominated by Neeraj Chopra with a gold medal performance in his second throw, while the other two athletes did not have any medal winning throws in these rounds.
(ii) The throws in the last round by both Jakub Vadlejch and Vitezlav Vesely were fouls and were not considered for scoring.
(iii) After four rounds, Vitezlav Vesely was in the second position and could not improve upon his best throw in the succeeding rounds.
(iv) In the fourth round, the throw by Jakub Vadlejch was the best in that round.
In which round did Vitezlav Vesely have his best throw?

Answer 1

Read the sentence as a rule: rain always brings out dancing peacocks, but the sentence never says dancing needs rain, and it never says no rain means no dancing. Test each option against a scenario where the rule still holds but peacocks dance for another reason, such as a nearby drum performance.

Peacocks dance only when it is raining: fails, because peacocks could also dance for the drum performance without any rain, so this option does not have to be true.
When peacocks dance, it is raining: fails for the same reason, dancing does not force rain.
When peacocks are not dancing, it is not raining: this must hold, because if it were raining the rule guarantees dancing, so no dancing rules out rain every time.
When it is not raining, peacocks do not dance: fails, since the drum-performance scenario has no rain but still has dancing.

Only the statement in option (C) survives every scenario consistent with the sentence, so it is the one that is necessarily true.
