Read the text and complete the sentences using the third conditional. Some scientists, such as Stephen Hawking, believe it‟s possible that there are billions and billions of universes.

Read the text and complete the sentences using the third conditional.

Some scientists, such as Stephen Hawking, believe it‟s possible that there are billions and billions of universes. Each universe has a different possible consequence for every action. In the universe we live in, for example, George Bush became President of the USA in January 2001, and Greece won the European Cup in July 2004. But in other universes different things happened. Imagine if that‟s true! In some universes, your parents didn‟t meet, so you weren‟t born. In another universe, a meteor didn‟t strike the Earth, so the dinosaurs didn‟t become extinct. In a different universe, your best friend won the lottery last summer and moved to a bigger house. In another parallel universe, you started learning English a year earlier, so you did this book last year! Somewhere else,

Madonna wasn‟t discovered, and so didn‟t make any records. In another universe, Van Gogh was recognised as a great painter during his lifetime, and so didn‟t die in poverty. And perhaps in several universes, there were enough lifeboats on the Titanic and so everyone on board survived. It makes you think, doesn‟t it?

1)If I‟d started learning English a year earlier, …

2)If a meteor hadn‟t struck the earth, …

3)If my best friend had won the lottery last summer, …..

4)If my parents ….

5)Everyone on board the Titanic ……..

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

  It’s a sound you will probably never hear, a sickened tree sending out a distress signal. But a group of scientists has heard the cries, and they think some insects also hear the trees and are drawn to them like vulture to a dying animal. Researchers with the US Department of Agriculture’s Forest Service fastened sensors to the bark of drought-stricken trees clearly heard distress calls. According to one of the scientists, most parched trees transmit their plight in the 50-hertz to 50kilohertz range. (The unaided human ear can detect no more than 20 kilohertz). Red oak, maple, white pine, and birch all make slightly different sounds in the form of vibrations at the surface of the wood.

 

   The scientists think that the vibrations are created when the water columns inside tubes that run along the length of the tree break, a result of too little water following through them.

 

   These fractured columns send out distinctive vibration patterns. Because some insects communicate at ultrasonic frequencies, they may pick up the trees' vibration and attack the weakened trees. Researchers are now running tests with potted trees that have been deprived of water to see if the sound is what attracts the insects. “Water-stressed trees also smell differently from other trees, and they experience thermal changes, so insects could be responding to something other than sound”, one scientist said.

Question: All the following are mentioned as possible factors in drawing insects to weakened trees EXCEPT______.

A. thermal changes

B. sounds

C. changes in color

D. smells
