(a/(b²-ab)+b/(a²-ab))*ab/(b+a)= (a/(b(b-a))+b/(a(a-b)))*ab/(b+a)= ((a²- b²)/ab(b-a))*ab/(b+a)= (-(a+b)/ab)*ab/(b+a)=-1

20. Read the text:
Most people were not impressed when in 1913 the Daily Mail newspaper offered 10.000 pounds to the first pilot to fly across the Atlántico under 72 hours. The majority of scientists even said it could not be done. Certainly the problems involved were many and far ranging. Obviously the design of the aero plane was of great importance, but so too were the skill and courage of the pilot and the navigator; weather conditions also had to be taken into consideration. A very few enthusiasts thought it might be possible ten years later. They were wrong. A pilot received the prize just six years later.
The correct answer: The passage point out that…
A) Many enthusiastic amateurs were eager to try.
B) The majority of scientists thought it could be done.
C) Many factors had to be considered.
D) The 10.000 pounds prize was offered ten years later.
E) The prize of £10.000 was not worth.
