When did the mongols rule china LOL

15 can someone translate this paragraph to german? (i created all and the incident went so complicated so most of them might not be senseful but the only important thing is translating not harmony of the text.)

Fill in the blank with the correct word to complete the sentence. der wird immer an einem sonntag im mai gefeiert. a. unabhängigkeitstag b. vatertag c. geburtstag d.  muttertag

Can someone tell me whether the word order in my sentence is correct? instagram und discord benutze ich jeden tag.
