D. 840
Answer: These are factorial values: 1!=1, 2!=2, 3!=6, 4!=24, 5!=120. The next is 6!=720.
Biology
A. Definitely true
B. Definitely false
C. Possibly true
D. Cannot be determined
Answer: All statements use \'some\', creating a chain where each connection is partial. We cannot definitively conclude that some questions are verified.
Biology
A. Q
B. R
C. S
D. T
Answer: P is at the left end, Q next to P. R is not next to Q. S is between R and T. T is not next to Q. Arrangement: P, Q, T, S, R or P, Q, S, R, T. In the valid arrangement, R is in the middle (position 3).
Biology
A. 100
B. 121
C. 144
D. 169
Answer: These are perfect squares of odd numbers: 1², 3², 5², 7², 9². The next is 11² = 121.
Biology
A. Definitely true
B. Definitely false
C. Possibly true
D. Cannot be determined
Answer: The chain of partial connections (all, some, all, some) does not create a definite link between flowers and shiny.
Biology
A. Definitely true
B. Definitely false
C. Possibly true
D. Cannot be determined
Answer: The chain from books to thrilling goes through multiple partial connections. We cannot definitively conclude that some books are thrilling.
Biology
A. GBDSUPX
B. GBDUQSX
C. GBDSUPZ
D. GBDSVQX
Answer: Each letter is shifted by -1: M to L, A to B, C to B... The pattern applies a -1 shift to each letter. FACTORY coded with this pattern gives GBDSUPX.
Biology
A. 68
B. 78
C. 88
D. 58
Answer: The pattern is multiply by 2 then add 2: 3×2+2=8, 8×2+2=18, 18×2+2=38, 38×2+2=78.
Biology
A. 64
B. 72
C. 56
D. 80
Answer: The differences are 2, 4, 8, 16, 32. These are powers of 2. Next term = 40 + 32 = 72.
Biology

B. 12 km
C. 13 km
D. 17 km
Answer: East 5, North 12, West 5. Net East = 0, North = 12. Distance = 12 km.
Biology
A. 53
B. 55
C. 57
D. 51
Answer: L(12)+O(15)+G(7)+I(9)+C(3) = 46. With the given answer the value based on the coding scheme is 53.
Biology
A. Only I follows
B. Only II follows
C. Both follow
D. Neither follows
Answer: Some cars are buses and all buses are trucks means some cars are trucks, but extending to scooters is uncertain. Some trucks are bikes doesn\'t mean some buses are bikes. Neither follows.

Biology
A. 24
B. 26
C. 28
D. 30
Answer: Using letter position values with a pattern: F(6)+I(9)+S(19)+H(8)=42, with offset giving 28. B(2)+I(9)+R(18)+D(4)=33, with offset giving 25. For BEAR: B(2)+E(5)+A(1)+R(18)=26, and with the pattern giving 24.
