Saving Bugs to Find New Drugs Solution
IELTS Cambridge 14, Test 3, Academic Reading Module, Reading Passage 2: Saving Bugs to Find New Drugs
QUESTIONS 14-20: READING PASSAGE 2 HAS NINE PARAGRAPHS, A-L.
14. ANSWER: C
· Key words: factors, renewed, interest, natural, medicinal, compounds
· The first sentence of paragraph C states that laboratory-based drug discovery has now “prompted the development of new approaches focusing once again on natural products”. The phrase “once again” implies that this interest in natural medicine had existed before, and now it is „renewed‟. So, this is one factor behind the renewed interest in natural products. Paragraph C then mentions another factor: “This realisation, together with several looming health crises, such as antibiotic resistance, has put bioprospecting – the search for useful compounds in nature – firmly back on the map”. The expression “back on the map” also refers to „a renewed interest‟.
· Drive = prompt
15. ANSWER: H
· Key words: recent, technological, advances, insect, research, easier
· The only paragraph which concerns technological advances is paragraph H: it is now possible to snip out insects‟ DNA and insert them into other cells that can produce larger quantities. The phrase “now possible” suggests that it wasn’t possible in the past, implying a great development in technology and science.
· The answer is H.
16. ANSWER: A
· Key words: examples, animals, medicinal, substances, nature
· Paragraph A gives examples of primates which use natural substances like toxin-oozing millipedes or noxious forest plants as medicine.
· Substances = compounds
· Nature = living things
17. ANSWER: F
· Key words: reasons, challenging, insects, drug, research
· Paragraph F discusses 3 reasons why it is very difficult, or challenging, to use insects in bioprospecting (which is the search for plant and animal species from which medicinal drugs and other commercially valuable compounds can be obtained).
· Challenging = daunting
· Drug research = bioprospecting
18. ANSWER: I
· Key words: interest, insect, research, benefit, wildlife
· The relation between insect research and wildlife (wilderness) can be found in paragraph I. The author claims that his main motivation for insect research is actually wildlife conservation, because “all species, however small and seemingly insignificant, have a right to exist for their own sake”. Thus, by showing the practical value of insect research, people would appreciate nature more, and wildlife in general will benefit.
19. ANSWER: B
· Key words: reason, nature-based, medicine, fell out of favour
· According to paragraph B: “for a while, modern pharmaceutical science moved its focus away from nature”
· For a period = for a while
· Medicine = pharmaceutical science
· The term “moved its focus away” means that natural medicine was no longer the focus of pharmaceutical science. Attention „shifted‟ to the design of chemical compounds in the laboratory. In other words, it fell out of favour.
20. ANSWER: E
· Key words: example, insect-derived, medicine
· Paragraph E mentions several promising compounds derived from insects, such as alloferon, which is used in Russia and South Korea. Hence, paragraph E gives an example of an insect-derived medicine in use at the moment.
QUESTIONS 21-22: CHOOSE TWO LETTERS, A-E.
Answer: B. the variety of substances insects have developed to protect themselves, C. the potential to extract and make use of insects‟ genetic codes
· Key words: what, make, insects, interesting, for, drug research
· Although using insects for drug research is challenging, it is also interesting and potentially useful. In paragraph G, the author mentions that many insects can release compounds to subdue their prey or to deal with pathogenic bacteria and fungi. This means that humans can make use of these compounds to produce antibiotics. Thus, B is one correct answer. Another benefit from insect research is that we can extract useful compounds by snipping out insect DNAs and inserting them into particular cells to allow larger production. Therefore, C is correct.
QUESTIONS 23-26: COMPLETE THE SUMMARY BELOW.
23. ANSWER: ECOLOGY
· 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
· 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
Overpower = subdue
· Preserve = keep it fresh
· Thus, it is clear that the answer is “prey”.
25. ANSWER: HABITALS
· 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
· 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
