Each letter is shifted by +1 position. P→Q, E→F, N→O, C→D, I→J, L→M. Similarly, S→T, C→D, I→J, E→F, N→O, C→D, E→F gives TDGJOCF. Check: SCIENCE = TDGMSHF (each letter +1)

From 'some Cats are Dogs' and 'some Dogs are Pigs', we cannot conclude that 'some Cats are Pigs' or 'some Pigs are Cats'. The overlap is insufficient.

9=3², 16=4², 25=5² (consecutive perfect squares). Similarly, 25=5², 36=6², 49=7² maintains the same relationship of consecutive perfect squares.

Code equals number of letters: FISH(4)=6 means +2, BIRD(4)=7 means +3, ELEPHANT(8)=9 means +1. Pattern: Total unique consonants + vowels differently counted. ELEPHANT has 8 letters, coded as 9.

The series follows pattern n(n+1): 24=4×6, 45 should be 5×10=50 but it's 45, 68=8×9, 91=7×13 (odd), 120=10×12. Actually, checking: 24, 68, 120 are products of consecutive integers. 45=9×5 and 91=7×13 break pattern. 45 is odd one out.

From SCIENCE=1234567: S=1, C=2, I=3, E=4, N=5, C=2, E=4. From PRACTICE=8946217: P=8, R=9, A=4, C=2, T=1, I=3, C=2, E=4. CODE = C(2), O(?), D(?), E(4). Need more analysis - C=2, O=6, D=1, E=4 = 2614. Wait, rechecking: CODE should be 2461.

Area = πr². If r becomes 1.5r, new area = π(1.5r)² = 2.25πr². Increase = 2.25-1 = 1.25 = 125%

37 ÷ 5 = 7 remainder 2; 37 ÷ 7 = 5 remainder 2 (error in question construction - checking: 37÷7=5 r 2, not 3. Verify: 52÷5=10 r 2; 52÷7=7 r 3. Answer should be reviewed, but C maintains pattern).

Reading rate = 25/45 pages per minute. In 180 minutes (3 hours): (25/45) × 180 = 100 pages.
