Cambridge ielts 1-15 series reading answers explained

 
 
 
20. Answer: i
This section mentions the funding of the project (“It has raised £340,000 in funding so far”) and its 
future prospects (“the company aims to be selling 1,000 units a month”). Thus, the most appropriate 
heading is i – „Getting the finance for production‟. 

finance = funding

QUESTIONS 21-26: COMPLETE THE SUMMARY BELOW. 
21. Answer: wheels
Key words: device, used, different locations, 
Section C explains how the desolenator works: “It measures 120 cm by 90 cm, and is easy to transport, 
thanks to its two wheels”. „easy to transport‟ has been paraphrased into „can be used in different 
locations‟. The feature that makes this possible is its „two wheels‟. However, as we can only use ONE 
WORD, the answer must be „wheels‟. 
22. Answer: film
Key words: water, fed, pipe, flows, solar panel
“Water enters through a pipe, and flows as a thin film between a sheet of double glazing and the 
surface of a solar panel”. After water enters a pipe (or is „fed into‟ a pipe), a thin film of water flows 
out, between „a sheet of double glazing and the surface of a solar panel‟. It can be inferred that the film 
of water flows over the surface of a solar panel. Therefore, the blank should be filled with „film‟. 
23. Answer: filter
Key words: any, particles, water, caught in
“The device has a very simple filter to trap particles”. 

catch = trap 
So this sentence can be paraphrased into the passive voice as „particles are trapped/caught in a very 
simple filter‟. The answer is „filter‟. 
24. Answer: waste
Key words: purified, water, tube, types, through another
This sentence distinguishes between two types of liquid that come out through two different tubes. In 
Section C: “There are two tubes for liquid coming out: one for the waste – salt from seawater, fluoride, 
etc. – and another for the distilled water”. The term „distilled water‟ is synonymous to „purified water‟, 
so the other type of liquid must be „waste‟. 

purified = distilled
