Let’s see how you’re doing! We’ll give you John’s first sentence. See if you can figure out where to slot も into in the second one!
昼ごはんにラーメンを食べました。
Hirugohan ni rāmen o tabemashita.
I ate ramen for lunch.
[___]昼ごはんに[___]ぎょうざ[___]食べました[___]。
[___] hirugohan ni [___] gyōza [___] tabemashita [___].
I also ate Chinese dumplings for lunch.
Answer: も should follow ぎょうざ[gyoza], since that’s the parallel element between the two sentences. John ate both of them!
