KEY

Question 1

            a) False. The bugs,.....  produce allergens which are easily inhaled during sleep.

            b) True. The warm, damp conditions created in an occupied bed are ideal for the creatures, but they are less likely to thrive when moisture is in shorter supply. (there are more justifications in the text.

He said that it was true that mites needed humid conditions to thrive and could not survive in very dry conditions.

c.The scientists developed a computer model to track how changes in the home can reduce numbers of dust mites in beds.
