the businesses ARE the economy (just saying)
No, the people are. Businesses would be nothing without consumers.
You're right ;)
" Businesses help the economy" Was not accepted, it is a typo, one correct answer was "Businesses helpaid the economy". I imagine this was meant to be aid or help.
Does anyone have a rule of thumb for when feminine nouns take -εις or ες in the plural? There seems to be a gap in my understanding of this!
