Which meaning means "the degree to which a string is tensed"?

• A. Tenacious
• B. Tentative
• C. Terse
• D. Tension

Answer: (D)

The main idea here is spotting which word best describes a physical state of being stretched tight. When we talk about how much a string is tensed, we’re describing its tautness—the amount of tension in the string. Tension is the noun that captures this state: the force along the string that makes it tight, so saying a string has high tension means it is very taut. The other words point to different ideas: tenacious means persistent or stubborn, not about a physical state; tentative means unsure or provisional; terse means brief or concise. So tension fits because it directly names the condition of being stretched tight.
