Questions & Answers about Сам учёный должен справляться, потому что в лесу бывают всякие опасности.
Why does this sentence use всякие instead of любые?
Любой implies a free choice ('any one you choose'), which does not make sense with dangers! Всякий, on the other hand, means 'all kinds of' or 'various'. Here, всякие опасности emphasizes that there is a wide, unpredictable variety of dangers in the forest, not that the scientist gets to pick one.
Why use бывают instead of just saying есть for 'there are'?
While есть just states the fact that something exists, бывать carries the meaning of 'to happen' or 'to occur from time to time'. Using бывают here implies that these various dangers crop up or tend to be there naturally, rather than just statically existing.
Why is the imperfective verb справляться (to cope) used here rather than the perfective справиться?
The sentence talks about a general expectation or an ongoing ability ('must be able to cope' generally), rather than succeeding at one specific, isolated task. When expressing a general rule or continuous state after должен, Russian prefers the imperfective aspect.
I know the prepositional case usually ends in -е. Why is it в лесу instead of в лесе?
