1. Mark took the farfel to the aircraft and left it there.
2. He drove back alone.
3. He transported the tsientsien and left it there.
4. He drove back with the farfel.
5. He transported the garble and left it there with the
tsientsien.
6. He drove back alone.
7. He transported the farfel

1. Tset said (in his first statement) that he did not throw
the rock and (in his third statement) that Zum lied by
saying he, Tset, did. Since only one of the three statements
could be false, both of these must be true. Therefore,
his second statement that Yan did it must be a lie.
So, we know that both Tset and Yan are innocent.
2. Zum said that Tset did it, and so we know that this
statement is Zum’s one lie. Therefore, Zum’s statement,
“I am innocent,” is the truth.
Who is left as a possible culprit? Pala and Uk.
3. Since Tset is innocent, Pala’s comment that Tset did it
was her lie. Therefore, her statements that she was innocent
and that she never saw Yan before were true.
4. Yan’s assertion that he and Pala were old friends was
therefore a lie. He told the truth when he said that he,
Yan, was innocent and that Uk was guilty

1. Aken said he was not a Uti. If he were a Uti, he couldn’t
say he was not one since Uti always tell the truth. So he
is definitely not a Uti. If he were a Yomi he couldn’t say
he was not a Uti since that would be the truth and the
Yomi always lie. So he cannot be a Yomi. Therefore,
Aken is a Grundi who sometimes tells the truth and
sometimes lies. And so we still don’t know what group
Doman belongs to.
2. Bal said he was not a Yomi. But is he a lying Yomi or a
truth-telling Uti? We don’t know yet.
3. Cwos said he was not a Grundi. Since each of the three
Martians belongs to a different group, and we already
know that Aken is the only Grundi among them, Cwos
must be telling the truth. Therefore Cwos is a Uti.
4. It follows that Bal must be a Yomi, because he lied by
denying that he is a Yomi.
5. Since Cwos is the truth-teller, Doman must be a Uti
because Cwos said he is.

You would be in 2nd place. You passed the person in second place, not first.

One. If he combines all his haystacks, they all become one big stack.

So let’s think this through. The ants can only avoid a collision if they all decide to move in the same direction (either clockwise or anti-clockwise). If the ants do not pick the same direction, there will definitely be a collision. Each ant has the option to either move clockwise or anti-clockwise. There is a one in two chance that an ant decides to pick a particular direction. Using simple probability calculations, we can determine the probability of no collision.

P(No collision) = P(All ants go in a clockwise direction) + P( All ants go in an anti-clockwise direction) = 0.5 * 0.5 * 0.5 + 0.5 * 0.5 * 0.5 = 0.25
