Which noun indicates a general decline in level or value?

• A. Downward trend
• B. Conveyor belt
• C. Knock down
• D. Demolish

Answer: (A)

When describing data over time, you want a noun phrase that captures the overall direction of change. A downward trend does this best because it signals that values are generally decreasing across the period, not just dipping briefly. It’s a standard, precise way to describe a pattern in IELTS and academic writing. The other options don’t fit as a description of data movement. A conveyor belt is just a machine, not a data-describing term. A knock down is typically a verb phrase meaning to reduce or defeat, and even when used as a noun it doesn’t convey a persistent pattern over time. Demolish refers to destroying structures, not describing numerical movement.
