The second group of trainee astronauts are all sitting around the table, waiting to start their first day of training.

From the clues given below, can work out where everyone sits?

Note: Seat 1 is next to Seat 2 and Seat 8, etc. Seat 5 is across from Seat 1, and Seat 7 is across from Seat 3, etc. Seat 2 is a higher seat number that Seat 1, etc.

Puzzle Table

1. Harvey has a higher seat number than Jennie.

2. Peter is across from Harvey.

3. Neither Joyce nor Lia is in seat 8.

4. Rick is across from Kenny, and Rick is also next to Joyce.

5. Lia is next to Kenny.

6. Jennie is at Seat 4 and next to Harvey.

7. Peter is next to Lia.

8. Mark has the remaining seat.

Seat 1: Peter Seat 2: Lia Seat 3: Kenny Seat 4: Jennie Seat 5: Harvey Seat 6: Joyce Seat 7: Rick Seat 8: Mark

Step-by-step explanation:

From Rule 6: Jennie is at Seat 4 and next to Harvey; and by rule 1 (Harvey has a higher seat number than Jennie)

Seat 4: Jennie Seat 5: Harvey

From Rule 2: Peter is across from Harvey.

Since Seat 5 is across from Seat 1

Seat 1: Peter

From Rule 7: Peter is next to Lia.

Therefore, Lia can either be in Seat 2 or Seat 8, but by Rule 3 (Neither Joyce nor Lia is in seat 8), therefore, Lia is in Seat 2.

Seat 2: Lia

By Rule 5: Lia is next to Kenny, therefore:

Seat 3: Kenny

From Rule 4: Rick is across from Kenny, and Rick is also next to Joyce.

Seat 7 is across from Seat 3, therefore:

Seat 7: Rick

Since Rick is also next to Joyce (and by Rule 3, Joyce cannot be on Seat 8)

Seat 6: Joyce

Therefore, we have:

Seat 1: Peter

Seat 2: Lia

Seat 3: Kenny

Seat 4: Jennie

Seat 5: Harvey

Seat 6: Joyce

Seat 7: Rick

Since Mark has the remaining seat, Mark is on Seat 8.
