Cambridge ielts 1-15 series reading answers explained

23-24. Answer: B. Some travel to overseas locations to join teams in zoos., D. Some teach people 
who are involved with conservation projects
Explain 
– Key words: two, stated, zoo staff 
– It is stated in paragraph D that: 
– “Many zoos also work directly to educate conservation workers in other 
countries” -> zoo staff can teach conservation workers, or people involved 
with conservation projects. So D is correct 
Teach = educate 
– “..or send their animal keepers abroad to contribute their knowledge and skills to those working in 
zoos and reserves”. This means that some animal keepers (a type of zoo staff) travel to overseas to 
help other zoo staff. 
– So B is correct 
25-26. Answer: B. They can increase public awareness of environmental issues., E. They can 
raise animals which can later be released into the wild.
Explain 
– Key words: two, beliefs, zoos 
– In paragraph B, it is stated that some animals have been reintroduced into the wild from zoos, or that 
wild populations have been increased by the 
introduction of captive bred animals. The term „reintroduce‟ means that 
animals will be raised in zoos before being released into the wild. 
– So E is correct. 
– Public = general population 
– Awareness = conscious 
– Thus, the sentence can be paraphrased into: zoos can increase public 
awareness of environmental issues. 
– B is correct.

27. Answer: FALSE 
Explain 
– Key words: Rochman, colleagues, first, research, marine, debris 
– Paragraph 2 mentions that “plenty of studies have sounded alarm bells about the state of marine 
debris” and that “Rochman and her colleagues set out to determine how many of those perceived risks 
are real”. This implies that there has been other research on marine debris before Rochman and her 
colleagues, and they want to examine these previous studies. 
– Thus, the statement is FALSE.
