- It is your third visit to Rio. Complete: "É a minha ___ vez no Rio."
Answer: terceira
'Vez' is feminine, so the ordinal is 'terceira'. 'Terceiro' is tempting, but ordinals agree in gender with the noun, and 'terceiro' goes with masculine nouns like 'dia'.
- How do you say "I need half a kilo of cheese" in Portuguese?
Answer: Preciso de meio quilo de queijo.
'Quilo' is masculine, so the adjective is 'meio': 'meio quilo'. 'Meia quilo' is tempting because people say 'meia dúzia', but 'meia' only goes with feminine nouns like 'dúzia' or 'hora'.
- Which phrase correctly says "200 pages" in Portuguese?
Answer: duzentas páginas
Hundreds from 200 up agree in gender, and 'páginas' is feminine plural, so 'duzentas páginas' is correct. 'Duzentos páginas' is the tempting error: the masculine form only goes with masculine nouns like 'livros'.
- You want to ask a new friend how many sisters she has. Complete: "___ irmãs você tem?"
Answer: Quantas
'Quantas' agrees with the feminine plural noun 'irmãs'. 'Quantos' is the most tempting choice, but it only goes with masculine nouns, as in 'quantos irmãos'.
- Complete to say your age: "Eu ___ quinze anos."
Answer: tenho
Portuguese uses 'ter' (to have) for age, and the 'eu' form is 'tenho'. 'Sou' is tempting because English says 'I am 15', but Portuguese literally says 'I have 15 years'.
