I. Choose the correct answer. Space experiment
Some exciting photos of space have recently appeared on the internet - all taken by teenagers!
Using a cheap camera and a simple balloon, some school students got a large (amount / sum / number / total)1 ………….. of amazing photos from 15 miles (among / above / about / along)2 ………….. Earth.
The teacher said, '(It / There / These / They)3 ………….. carried out an experiment to explore what different (positions / distances / areas / backgrounds)4 ………….. on the Earth look like from space - and prove that you don’t have to use expensive equipment as the textbooks say.’
Seventeen-year-old student Miguel reported, ‘We’d spent long (times / hours / ages / days)5 ………….. working on the experiment after school, but then had to put it (off / down / out / up)6 ………….. due to the weather. Then we were worried that the balloon (shouldn’t / needn’t / mustn’t / wouldn’t)7 ………….. rise higher than 10,000 metres, which wasn’t (quite / so / rather / very)8 ………….. high enough for our experiment. But in the end it wasn’t a problem. And (unless / although / because / if)9 ………….. the balloon had travelled so far, it was still working when it returned! So we’ve learned that in (true / actual / normal / real)10 ………….. life, experiments don’t always have to follow the textbooks!’
