what is the meaning of impractical in the following sentence? shellys plan was too impractical for us to do.
impractical means not realistically able to be done.
impractical means having qualities of uniqueness.
impractical is someone who creates something.

Explanation:

To determine the meaning of "impractical", we analyze its word parts. The prefix "im - " (a variant of "un - ") means "not", and the suffix "-able" means "capable of being". The root "practical" relates to what can be done. So "impractical" combines "not" + "capable of being practical" (practical here meaning feasible to do). The sentence context ("too...for us to do") also supports this, as it implies the plan can't be realistically done. The other options don't match: "having qualities of uniqueness" doesn't relate to "impractical", and "someone who creates something" is incorrect as "-ical" here pertains to a quality, not a person (which would use "-er/-or").

Answer:

A. Impractical means not realistically able to be done.
