Which term means 'sparring or economical in use or expenditure'?

• A. fundamental
• B. furthermore
• C. gallant
• D. frugal

Answer: (D)

The idea being tested is choosing a word that describes using resources carefully and without waste. Frugal is the best match because it specifically means sparing or economical in the use of money, time, or materials—thrifty and prudent rather than wasteful. For example, someone who plans meals to avoid waste and shops for bargains is being frugal.

Other options don’t fit this sense: fundamental describes something essential or foundational, not about usage; furthermore is a transition word meaning “in addition,” not a descriptor of how something is used; gallant means brave or courteous, not related to economy of resources. So frugal directly captures the intended meaning.
