Reading Answer of Cork

Answers Keywords Location Explanation
1. NOT GIVEN Thickest bark Paragraph 2, line 2 The author mentioned the thick bark of the cork oak tree
as a remarkable material and its bark grows up to 20 cm in thickness.

 

This information does not mean that it is the thickest bark of any living tree.

2. FALSE A synthetic cork, the same cellular structure paragraph 2 line 8 The writer mentioned the cellular structure of the bark of the cork oak “the bark of the cork oak has a particular cellular structure – with about 40 million cells per cubic centimeter – that technology has never succeeded in replicating”.

 

  • technology = scientists
  • never succeeded in replicating= have not been able to make a copy of the natural cork
3. FALSE Individual, 25 years paragraph 4 line 6 From the planting of a cork sapling to the first harvest takes 25 years, and a gap of approximately a decade must separate harvests from an individual tree.

 

  • Therefore, the period of 25 years is the period from the planting to the first harvest, while the gap between the first and the second harvest is about 10 years ( a decade)
4. TRUE Stripped, atmospheric conditions​ paragraph 4 line 14 If the bark is stripped on a day when it’s too cold – or when the air is damp – the tree will be damaged.

 

Therefore, the bark should not be stripped in damp atmospheric conditions but in dry .

5. TRUE Only way, remove, by hand​ paragraph 5 line 2 No mechanical means of stripping cork bark has been invented, so the job is done by teams of highly skilled workers.

 

  • “stripping cork bark” = “remove the bark”.
  • no mechanical means has been invented”=  no use of any machines in removing the bark
  • By hand = done by workers, no mechanical means
6.Taste affect, bottle contents paragraph 6 line 1 Recent years have seen the end of the virtual monopoly of cork as the material for bottle stoppers, due to ……………..can spoil the taste of the product contained in the bottle. The result has been a gradual yet steady move first towards plastic stoppers and, more recently, to aluminum screw caps.

 

  • Affect = spoil
  • Bottle contents = the product contained in the bottle

Moved from cork to plastic and recently to aluminium for not spoiling the taste.

7.Cheaper Produce paragraph 6 line 17 These substitutes are cheaper to manufacture.

 

  • Cheaper= manufacture
8. Convenient Use​ paragraph 6 line 17 These substitutes are cheaper to manufacture and, in the case of screw caps, more convenient for the user”.
9. image Suit, quality products paragraph 7 line 3 Firstly, it’s (the cork bottle stopper) traditional image is more in keeping with that of the type of high-quality goods with which it has long been associated.

 

  • The answer allows one word only, so it has to be “image”
    • Products = goods
    • In keeping with = suit
10.Sustainable  Made from, material Paragraph 7 line 6 Secondly and very important cork is a sustainable product ….
11.Recycled   Paragraph 7 line 6 Secondly – and very importantly – cork is a sustainable product that can be recycled without difficulty

 

  • Easily = without difficulty
12.Biodiversity Cork forests, aid   Moreover, cork forests are a resource which supports local biodiversity, and prevent desertification…………….

 

  • aids= supports

For one word answer= biodiversity

13. Desertification. cork forests, stop​ paragraph 7 line 9 Moreover, cork forests are a resource which supports local biodiversity, and prevent desertification in the regions …………..

 

  • stop = prevent

You should spend about 20 minutes on Questions 1- 13, which are based on Passage below.

Cork

Cork – the thick bark of the cork oak tree (Quercus suber) – is a remarkable material. It is tough, elastic, buoyant, and fire-resistant, and suitable for a wide range of purposes. It has also been used for millennia: the ancient Egyptians sealed then sarcophagi (stone coffins) with cork, while the ancient Greeks and Romans used it for anything from beehives to sandals.

And the cork oak itself is an extraordinary tree. Its bark grows up to 20 cm in thickness, insulating the tree like a coat wrapped around the trunk and branches and keeping the inside at a constant 20°C all year round. Developed most probably as a defence against forest fires, the bark of the cork oak has a particular cellular structure – with about 40 million cells per cubic centimetre – that technology has never succeeded in replicating. The cells are filled with air, which is why cork is so buoyant. It also has an elasticity that means you can squash it and watch it spring back to its original size and shape when you release the pressure.

Cork oaks grow in a number of Mediterranean countries, including Portugal, Spain, Italy, Greece and Morocco. They flourish in warm, sunny climates where there is a minimum of 400 millimetres of rain per year, and no more than 800 millimetres. Like grape vines, the trees thrive in poor soil, putting down deep root in search of moisture and nutrients. Southern Portugal’s Alentejo region meets all of these requirements, which explains why, by the early 20th century, this region had become the world’s largest producer of cork, and why today it accounts for roughly half of all cork production around the world.

Most cork forests are family-owned. Many of these family businesses, and indeed many of the trees themselves, are around 200 years old. Cork production is, above all, an exercise in patience. From the planting of a cork sapling to the first harvest takes 25 years, and a gap of approximately a decade must separate harvests from an individual tree. And for top-quality cork, it’s necessary to wait a further 15 or 20 years. You even have to wait for the right kind of summer’s day to harvest cork. If the bark is stripped on a day when it’s too cold – or when the air is damp – the tree will be damaged.

Cork harvesting is a very specialised profession. No mechanical means of stripping cork bark has been invented, so the job is done by teams of highly skilled workers. First, they make vertical cuts down the bark using small sharp axes, then lever it away in pieces as large as they can manage. The most skilful cork- strippers prise away a semi-circular husk that runs the length of the trunk from just above ground level to the first branches. It is then dried on the ground for about four months, before being taken to factories, where it is boiled to kill any insects that might remain in the cork. Over 60% of cork then goes on to be made into traditional bottle stoppers, with most of the remainder being used in the construction trade, Corkboard and cork tiles are ideal for thermal and acoustic insulation, while granules of cork are used in the manufacture of concrete.

Recent years have seen the end of the virtual monopoly of cork as the material for bottle stoppers, due to concerns about the effect it may have on the contents of the bottle. This is caused by a chemical compound called 2,4,6-trichloroanisole (TCA), which forms through the interaction of plant phenols, chlorine and mould. The tiniest concentrations – as little as three or four parts to a trillion – can spoil the taste of the product contained in the bottle. The result has been a gradual yet steady move first towards plastic stoppers and, more recently, to aluminium screw caps. These substitutes are cheaper to manufacture and, in the case of screw caps, more convenient for the user.

The classic cork stopper does have several advantages, however. Firstly, its traditional image is more in keeping with that of the type of high quality goods with which it has long been associated. Secondly – and very importantly – cork is a sustainable product that can be recycled without difficulty. Moreover, cork forests are a resource which supports local biodiversity, and prevents desertification in the regions where they are planted. So, given the current concerns about environmental issues, the future of this ancient material once again looks promising.
