1. Misha's project started

The question asks when Misha's project started. The options are 'last week', 'last month', 'last year', and 'yesterday'. Without further context from a story or passage, any of these could be correct. However, in typical multiple-choice questions of this nature, there is often an implied context or a most common scenario. If this is a standalone question, it is unanswerable. Assuming there is missing context that would point to one answer, and without that context, I cannot definitively choose. However, if forced to guess based on common phrasing, 'last month' or 'last year' are frequent timeframes for projects. Since I must provide an answer, and lacking context, I will select 'last month' as a plausible option.
