Hey hope your doing well, the agro market is super simple it just confused you because if the name, it means agricultural marketing. It’s just agriculture food and products for sale at a market.
Noun, like a person place or thing.
So, in the 1st one you would list 'Radio, Inventors, and Television'
Hope I helped :)
Have a nice Day!

I believe the correct answer is exercitui.
You need the perfect passive form here, which is formed when you combine the verb esse in the present tense (here, sunt because of third person plural), and the appropriate participle in the same person, which in this case is exercitui - third person plural.
