1. (+) Mr .Muhammad prayer at this mosque this morning ,negatif dan introgativnya apa ya ? 2.(+) Fenny sent her letter at this post office negatif dan introgati

** nomor 1 dilihat dari keterangan waktunya "this morning" dan nomor 2 dilihat dari kata kerjanya "sent" saya anggap sebagai kalimat simple past tense.
pola kalimatnya (untuk kata kerja)
(+) Subject + Verb2 + Complement
(-) Subject + did not(didn't) + Verb1 + Complement
(?) Did + Subject + Verb1 + Complement

1. (-) Mr. Muhammad didn't pray at this mosque this morning.
(?) Did Mr. Muhammad pray at this mosque this morning?

2. (-) Fenny didn't send her letter at this post office.
(?) Did Fenny send her letter at this post office?

maaf nomor 3 kalimatnya tidak jelas, jadi tidak bisa saya kerjakan.
