Answer 1

A play is a piece of writing which can be SEEN at a theatre or on television, or heard on the radio.
⇒ perhatikan kata 'can be'. ini menunjukkan modals passive, sehingga kata kerja yang dibutuhkan adalah v3.

A director HELPS the actors to work better, or tells them how he wants the play to be.
⇒ perhatikan anak kalimat yang berkata kerja "tells". sehingga, induk kalimatnya berbentuk simple present dengan subject 'a director'. (ini cara bodohnya)

But the director can change the play in different ways: the actors costume, the music, how people say things, how they MOVE or what they hold
⇒ sama seperti no 2, perhatikan kata kerja sebelumnya "say", sehingga jawabannya juga kata kerja berbentuk simple present dengan subject 'they'
