This excerpt contains four sentences of fact and zero sentences of opinion.
Explanation:
The main difference between facts and opinions is, basically, that the facts are described without any subjective tinge, that is, without any personal burden on the part of the author when describing the events that occurred; whereas the opinion is the description of an event with all a subjective load, implying a personal analysis of the facts and a series of individual considerations about them.
In this case, the excerpt is limited to a description of the events and their implications, without mentioning at any time the personal position of the author on them, so that said fragment does not have any opinion.
