1. What benefits might the new compound have for farmers in tropical countries?

They might double their production of potatoes.

They might be able to grow new crops.

Their crops would receive less UV rays.

The new compound could potentially benefit farmers in tropical countries by allowing them to grow new crops. This suggests that the compound may have properties that enable plants to thrive in tropical climates, expanding the range of crops that can be cultivated. This would provide farmers with more options and potentially increase their income and food production.

2. What has Dr Wilkinson discovered in the last five years?

That a new substance is created when coral and algae interact

That coral in certain oceans can protect itself

That algae living on coral, modifies the coral

Dr Wilkinson has discovered that when coral and algae interact, a new substance is created. This suggests that there is a chemical reaction or process occurring between the coral and algae that results in the formation of a different substance. This finding could have implications for understanding the relationship between coral and algae and how they contribute to the overall ecosystem.

3. Listen to an interview with a British scientist. Choose the best answers, A, B or C. What is Dr Wilkinson trying to do?

Invent a cream to protect people from the sun

Reduce the number of people sunbathing

Create a tablet that works like sun cream

Dr Wilkinson is trying to create a tablet that works like sun cream. This means that he is working on developing a tablet that can provide protection against the sun's harmful rays, similar to how sun cream does.

4. After they know what the new compound is, what is the next stage in the process?

To test the new compound on cosmetic surgeons

To decide how much of the compound is needed for each pill

To carry out tests of the compound on samples of skin

The next stage in the process after knowing what the new compound is would be to carry out tests of the compound on samples of skin. This step is necessary to evaluate the potential effects and effectiveness of the compound on the skin. Testing on samples of skin allows researchers to gather data and observe any reactions or benefits of the compound before proceeding further in the development process.

10. Dr Wilkinson hopes to extend his research to countries where crops are exposed to high levels of _____ .

Dr. Wilkinson aims to expand his research to countries where crops are subjected to high levels of sunlight, UV rays, and ultraviolet rays. This suggests that he wants to investigate the effects of these specific elements on crops in different regions. By studying crops in areas with intense sunlight and high levels of UV radiation, Dr. Wilkinson can gain insights into how these environmental factors impact crop growth, development, and overall health.
