1. Nam asked what to wear to the fancy dress party.

→→ Riêng với từ should trong trường hợp hai mệnh đề đều chỉ một người thì có thể rút gọn thành: S+to + V+(O).

2. Mi said Phong that she felt stressed and tensed to see that she couodn't get the perfect results.

→→ Hiện tại đơn lùi thì quá khứ đơn: S+Ved/Vp1+(O).
