The first group of trainee astronauts are all sitting around the rectangular table, waiting to start their first day of training.
From the clues given below, can work out where everyone sits?
The seats are numbered clockwise, with Seat 1 next to Seats 2 and 8. Opposite pairs are Seats 1 & 5, 2 & 8, 3 & 7, and 4 & 6.
William is next to Alisa and Nick. William is across from George. Amanda is next to Sarah. Sarah is across from Eric. Nick is next to Eric. Sydney is in Seat 4 and sits next to George. George has a higher seat number than Sydney. Alisa is not in Seat 2.
Answer
Seat 1 = William
Seat 2 = Nick
Seat 3 = Eric
Seat 4 = Sydney
Seat 5 = George
Seat 6 = Amanda
Seat 7 = Sarah
Seat 8 = Alisa
Reasoning
Sydney is in Seat 4 and is next to George (Clue 6), so George is in either Seat 3 or Seat 5. But George has a higher seat number than Sydney (Clue 7). Therefore, George is in Seat 5.
William is across from George (Clue 2), and therefore is in Seat 1.
William is next to Alisa and Nick (Clue 1), so Alisa and Nick are in Seat 2 and Seat 8 (either way around). But Alisa is not in Seat 2 (Clue 8). Therefore, Alisa is in Seat 8 and Nick is in Seat 2.
Nick is next to Eric (Clue 5) so can only be in Seat 3.
Sarah is across from Eric (Clue 4), and therefore is in Seat 7.
Amanda is next to Sarah (Clue 3) and can only be in Seat 6.

During an exciting weekend of paintball, four friends were having great fun.
The paintballs came in blue, green, yellow, and red.
Coincidentally, the four friends had T-shirts in those same colours.
Billie used blue paintballs. The person in the green T-shirt used yellow paintballs. Charlie was not wearing a red T-shirt. Drew used green paintballs and wore a blue T-shirt. Alex was the only person who used paint which was the same colour as their T-shirt.
Can you tell which colour paint they each used and the colour of their respective T-shirts?
