What does the term 'viable' mean in the context of: 'Solar energy represents an economically viable alternative for desert communities'?
Answer and explanation
Correct answer: D. Capable of working successfully and feasibility
- Step 1: Examine contextual clues: The text describes solar energy as a positive alternative for sunny desert areas.
- Step 2: Define 'viable': Capable of surviving, developing successfully, or being implemented practicably and economically.
- Step 3: Confirm definition: Capable of working successfully and feasible.
Answer
Capable of working successfully and feasibility.
Why not the others: 'expensive' contradicts practical viability; 'obsolete' is the exact antonym of a modern alternative; 'devoid of resources' describes scarcity rather than operational capability.
