Question

Polygraph tests _____ accepted in court cases.

• A. have been
• B. will have
• C. were used
• D. are known

Answer 1

Answer:

A. have been

• ഇവിടെ subject( polygraph tests) plural ആയതുകൊണ്ട് അതിനു ശേഷം plural verb എഴുതണം. This is a passive construction: "Polygraph tests have been accepted in court cases."

Passive Voice Structure:

• Structure: Subject + form of "to be" + past participle

Analysis:

• Subject: Polygraph tests
• Form of "to be": have been
• Past Participle: accepted

Why It’s Passive:

• The subject ("polygraph tests") is not performing the action; it’s receiving it.
• The form "have been" combined with the past participle "accepted" creates a passive construction.
