Answer 2

Make the thing. It's a singular imperative. The root word facio, facere is a well-used verb in Latin, and has several possible meanings. You can't tell which without the context:

facio, facere - make/build/construct; create/cause/do;
have built/made; fashion; work (metal);
act/take action/be active; (bowels); act/work (things), function, be effective;
produce; produce by growth; bring forth (young); create, bring into existence;
compose/write; classify; provide; do/perform; commit crime; suppose/imagine;

Any of those could be the verb.
