In a code language, LOGIC is written as MPHJD. How is REASON written in that code?

Answer: SFBTPO

Each letter is shifted forward by 1 (L→M, O→P, G→H, I→J, C→D), so R→S, E→F, A→B, S→T, O→P, N→O gives SFBTPO.

A 3×3 grid is filled with numbers sequentially left to right, top to bottom starting from 1. What number belongs in the bottom-right cell?

Given: A > B, B = C, C < D. What is the relationship between A and D?

A train 120 meters long passes a stationary pole in 12 seconds. How long will it take the same train to pass a 240-meter platform?

Answer: 36 seconds

The train's speed is 120 ÷ 12 = 10 m/s; to pass the platform it must cover 120 + 240 = 360 m, taking 360 ÷ 10 = 36 seconds.

Statement: The city should ban single-use plastics to reduce pollution. Which argument most weakens this conclusion?
