Choose the most appropriate option to fill the blank in the given sentence. Radium ___ rays that can damage the eyes.
- (a)gives over
- (b)gives up
- (c)gives off
- (d)gives away
Answer
Why
Correct — C. Give off means to send out or emit: heat, light, a smell, gas or radiation.
Radium is a radioactive element, and what it does with rays is emit them: Radium gives off rays that can damage the eyes.
The verb is the same in all four options, so the particle decides, and only off carries the sense of emitting. That is option (c).
Why the others are wrong
- (a)gives over — Give over means to hand something over to someone, or, in the passive, to set it aside for a use (a hall given over to exhibitions). Radium hands nothing over.
- (b)gives up — Give up means to stop doing something or to surrender it (give up smoking). Radium does not stop or surrender rays; it sends them out.
- (d)gives away — Give away means to hand out free, or to reveal a secret. Rays leaving radium are neither a gift nor a disclosure.
Concept
A phrasal verb is a verb plus a particle, and the pair can mean something the verb alone does not. With give, the particle does all the work:
give off = emit (a smell, heat, radiation)
give up = stop, or surrender
give away = hand out free, or reveal
give over = hand over, or set aside for a use
Read the object of the blank first: rays are something a source emits.
Key facts
- Give off: to emit heat, light, a smell, gas or radiation (the flowers gave off a sweet scent).
- Give away: to give something free, or to reveal what was meant to be secret.
- Give up: to stop doing something, or to surrender it (give up smoking).

Common traps
- Choosing give away because the rays leave the radium: give away needs a sense of gift or disclosure.
- Guessing from the verb when every option has the same verb: only the particle can decide.
