They made me confused:
Supply the correct word form:
1> A(n) ............ of food poisoning led to the death of five people. ( BREAK)
2> India's population now ........... that of Africa. ( PASS )
3> She's ................... all her school clothes. ( GROWTH )
4> The Concord was a type of ................. airplane. ( SOUND )
5> She ................... her husband by two years. ( LIFE )
6> With a .................. effort, Bill managed to control his temper. ( HUMAN)
7> He decided to do the job because the possible benefits ............... the risks involved.
( WEIGHT )
8> Scientists still cannot explain some ................. phenomena. ( NATURE )

I can't even have an idea what words I must use. I think (1) is "breakfast", (4) is " sonic", and (8) is "unnatural", but I am not sure.
They are too difficult to me, please help, thanks.
Kind regards,

Okay, you were on the right track with number 8, I think the initial root word needs to be complemented with a prefix like this :
DarkmasterThey made me confused: Supply the correct word form:
1> A(n) OUTBREAK of food poisoning led to the death of five people. ( BREAK)
2> India's population now SURPASSES that of Africa. ( PASS )
3> She's OUTGROWING all her school clothes. ( GROWTH )
4> The Concord was a type of SUPERSONIC airplane. ( SOUND )
5> She OUTLIVED her husband by two years. ( LIFE )
6> With a SURHUMAN (????) effort, Bill managed to control his temper. ( HUMAN)
7> He decided to do the job because the possible benefits OUTWEIGH the risks involved. ( WEIGHT )
8> Scientists still cannot explain some UNNATURAL phenomena. ( NATURE )
I'm not sure about number 6 though. This has to be something that means 'more than human' but which exact prefix is appropriate, that I don't know...

Hope this helps ?

I think "superhuman" is what you're looking for. Emotion: smile

There's an other possibility for 3.: "She's outgrown etc"

I'd prefer "supernatural" for 8.

Thanks a lot.

PieAnne,

Yes SUPER is definitely what it is... and what you are...
How come I didn't think of it...

Waïti.
This is an exercise in the use of prefixes that mean something like "more than", which are "out-", "super-", and "sur-". "sur-" is used in the second example. All the rest use either "out-" (outbreak, outgrown, outlived, outweigh) or "super-" (supersonic, superhuman, supernatural).
