'Ought to' & expectation

[Explorer]

'He ought to solve the problem this week'.

I see three ways how 'ought to' can be interpreted

1. The event is expected to happen due to the circumstances.
2. The event is expected to happen due to the features of 'he'.
3. The event is expected to happen due to the circumstances where the circumstances comprise the features of 'he'.

What is the right version?

Thank you in advance.

None of the above is correct.

'He is expected to solve the problem this week'.

But what does prompt an Englihspeaker to say 'He ought to solve the problem this week' - the fact that 'he' is a smart guy or, eg. the fact that 'he' has good instruments?

(In another words why is 'he' expected to solve the problem this week - because 'he' is a smart guy or, eg. becaue 'he' has good instruments?).

It could be the qualities of the person, the tools available, a duty, etc.
