Capable of working successfully or being put into practice.
“Solar power has become a viable alternative for many rural communities.”
“The committee is exploring whether a four-day work week is a viable option for staff.”
In Part 3 articles, "viable" often describes a solution, option, or plan being evaluated, which is helpful for questions asking about feasibility or practicality. Since Part 3 passages sometimes weigh multiple options, look for this word to identify the paragraph discussing which choice is realistic. It usually contrasts with impractical or failed alternatives mentioned elsewhere in the article.
Synonyms: feasible, workable, practical
