Researchers have successfully mapped the genetic code of the mouse and have generously elected to make their findings available to scientists everywhere. A genetic model of the mouse is of benefit to researchers because it is believed that one hundred million years ago, both mice and humans shared a common rodent-like ancestor. This makes mice ideal substitutes for humans in genetic studies. Therefore, the mouse is one of the most useful animals for studying cancer and other diseases.

1.The research findings show that humans and mice once had a common ancestor.

• Box A : ‘True’ statement
• Box B : ‘False’ statement 
• Box C :‘Can’t tell’

  2. It is likely that these findings, due to a similar shared genetic code, will result in research that will lead to the eradication of cancer.

The technological advances that sparked the current revolution were the result of military research at the end of World War II, but advances continued at an accelerating rate through the succeeding years and have sustained the original inspiration in what appears to be an endless succession of inventions. Half of the scientific research conducted in United States since the Republic was founded has been crowded into the last eight years; 90 percent of all the scientists who have ever lived in the history of mankind are alive today. 
1. Military research stimulates technological advances.
