Read the following information carefully and answer the questions which follow.
Eight friends A, B, C, D, E, F, G and H are sitting in a straight row. All of them are facing north. A is third to the left of H and second to the right of C. G and D are sitting adjacent to each and there are more people to the right of G than to his left. Neither F nor H are sitting at the end positions and E is sitting to the left of A but he is not sitting at an end position.
Who is sitting second to the left of B?
Eight people are sitting in a straight line. Let us number the positions as 1 to 8 from left to right. A is second to the right of C and third to the left of H. Moreover, H is not sitting at an end position. So, the possibilities for C, A and H are 2, 4, 7 or 1, 3, 6. If they are sitting at 2, 4,7, then D and G must be sitting at 5 and 6. Now, F is not sitting at an end position, so the only possible place for him will be 3. In this case E will have to sit at 1. But contradicts the given information. Hence, this is not possible. Thus, C, A and H must be sitting at 1, 3 and 6 respectively. D and G can be 4/5 or 7/8. But in case of 7/8, there won’t be more people to the right of G then his left. Hence G must be fourth, D must be fifth. E must be 2. B should be at 8 and F should be at 7. Thus, we will have the following arrangement
How many people are sitting between F and A?

In the upcoming Laver Cup, eight players—four from Europe and four from the rest of the world—are to be seated around a round table. Each player is either facing the table or facing away. A player who faces the table does not sit adjacent to another player who is also facing the table. No European player sits facing away from the table. Players seed 1 and 2 are seated directly opposite facing each other. Furthermore, for each pair of players sitting opposite one another, the sum of their seeds is a prime number. The players seeded 3 and 8 are positioned on either side of the first seed, while the player to the right of the second seed is not a top 4 seed, and to left of that player, who is not a top 4 seed is a player who is not a bottom two seed.
Which of the following statements is definitely FALSE?
From the clue given that a player who faces the table does not sit adjacent to someone who also faces the table, we understand that the directions alternate for the players around the round table. The configuration would look like,
Now we are given that only European players face the table, and that seed 1 and 2 are facing each other. That means seed 1 and 2 are European. It is also given that pairs sitting opposite to each other, have their sum of seeds add up to a prime number.
Before doing trial and error, we look at the next clue that says that seeds 3 and 8 sit on either side of seed 1, so that means seed 3 and 8 are not Europeans and 3 and 8 are not sitting opposite to each other.
Now that 3 and 8 cannot be a prime number sum pair, we look at the only other possible option of pairs.
1 and 2 (given)
3 and 4
5 and 8
6 and 7
We have the following arrangement using the clues thus far,
Now we look at the clue that says that the player to the right of the second seed is not a top 4 seed. So, we see the possible configurations, we observe that either 4 or 5 can be placed adjacent to seed 2, that means seed 5 is to the right of seed 2. And the second part of that clue says, the player to the left of that player is not bottom 2. To the left of the 5th seed (considering the fact the player is facing away from the table) is either 6 or 7, since it is said not bottom 2, it is 6th seed. And using the prime number configuration we can find the remaining two players as well.
The final configuration using all the clues is as follows.
We see that 6 does not sit adjacent to 4.
Who out of the following players is NOT European?
From the clue given that a player who faces the table does not sit adjacent to someone who also faces the table, we understand that the directions alternate for the players around the round table. The configuration would look like,
