"Are you poor?"
Wow. A lot of combinations are possible:
"Ești sărac?" (singular masculine)
"Ești săracă?" (singular feminine)
"Sunteți săraci?" (plural masculine/mixed)
"Sunteți sărace?" (plural feminine)
This is because the English sentence is ambiguous in these regards, and you need some context to know which combination it refers to.
Context would be amazing, unless they want us to fail these and/or memorize the answers...
