The correct answer is: Only conclusion II follows.
The first statement is “All artists are smokers.” This means that if something is an artist, then it must also be a smoker. The second statement is “Some smokers are drunkards.” This means that there are some people who smoke and are also drunkards.
From these two statements, we can conclude that some drunkards are artists. This is because the second statement tells us that there are some people who smoke and are also drunkards. The first statement tells us that all artists are smokers. Therefore, some of the people who smoke and are also drunkards must be artists.
However, we cannot conclude that all smokers are artists. This is because the first statement only tells us that all artists are smokers. It does not tell us that all smokers are artists. It is possible that there are some people who smoke but are not artists.
Therefore, the only conclusion that follows from the given statements is that some drunkards are artists. Conclusion I, “All smokers are artists,” does not follow. Conclusion II, “Some drunkards are not smokers,” does follow.
