Questions & Answers about Они ликвидировали проблему очень быстро.

How can we tell if ликвидировали is perfective or imperfective in this sentence?
Ликвидировать is a biaspectual verb, meaning it uses the exact same form for both aspects. In this sentence, the context provides the answer: the adverb phrase очень быстро (very quickly) and the clear focus on a successfully completed result tell us it is functioning as a perfective verb here.
What context would make ликвидировали act as an imperfective verb instead?
If we changed the context to focus on an ongoing or repeated process, it would be imperfective. For example, if the sentence said Они ликвидировали эту проблему годами (They were eliminating this problem for years), the time phrase forces the imperfective meaning.
Why do verbs like ликвидировать often lack separate aspect pairs?
Many verbs borrowed from foreign languages are adapted into Russian using the suffix -ировать. Because they do not originate with native Russian prefixes to easily mark the perfective aspect, they often enter the language as biaspectual. While some eventually develop native-looking pairs, ликвидировать remains dual-aspect.
Is ликвидировать проблему the most natural way to say 'fix a problem' in daily life?
It is grammatically correct but sounds quite formal, bureaucratic, or technical, much like 'eliminate a problem' in English. In everyday conversational Russian, you are much more likely to hear решить проблему (to solve a problem) or устранить проблему (to remove or fix a problem).
