Cambridge ielts 1-15 series reading answers explained

23. Answer: ecology
Explain 
· Key words: Ross Piper, zoologists, Aberystwyth University, expertise, bioprospecting, insects 
· Using the skim and scan skill, we can find information about Aberystwyth University scientists in 
paragraph G. There, Piper and his colleagues use their knowledge in ecology to target certain insects 
for bioprospecting. 
· Expertise = knowledge 
24. Answer: prey
Explain 
· Key words: interested, compounds, insects, produce, overpower, preserve 
· The creatures that particularly interest the scientists are those that product substances to subdue 
their prey and to keep it fresh. 
· Especially = particularly = đặc biệt 
· Overpower = subdue = chinh phục

· Preserve = keep it fresh = bảo quản 
· Thus, it is clear that the answer is “prey”. 
25. Answer: habitals
Explain 
· Key words: interested, compounds, insects, protect, pathogenic bacteria, fungi, found 
· The insects that have to product compounds to fight against pathogenic bacteria and fungi, as well 
as other micro-organisms, usually live in filthy habitats. Thus, it can be understood that pathogenic 
bacteria and fungi are found in these insects‟ habitats. Note that we cannot use “filthy habitats” 
because only one word is allowed. 
26. Answer: antibiotics
Explain 
· Key words: Piper, hopes, useful, development, drugs 
· Piper (the author) states that “there is certainly potential to find many compounds that can serve as 
or inspire new antibiotics”. This means he hopes that these compounds and substances will be used to 
develop antibiotics (a type of drug). The answer is “antibiotics”. 
· Be useful = serve 
THE POWER OF PLAY
27. Answer: B
Explain 
· Key words: play, divided, separate, categories 
· According to Miller & Almon (paragraph 4), there are “discrete descriptions of various types of 
play such as physical, construction, language or symbolic play”. This means that play can be divided 
into various types or categories. 
· The answer is
