How did Mrs frisby escape?

In the book "Mrs. Frisby and the Rats of NIMH" by Robert C. O'Brien, Mrs. Frisby escapes from the farmer's plow by seeking help from the rats of NIMH. The rats, who have gained intelligence and abilities through scientific experiments conducted on them at the National Institute of Mental Health (NIMH), agree to help Mrs. Frisby. They devise a plan to move her house to a safer location before the plow arrives.

Using their advanced technology and knowledge, the rats construct a system of pulleys and ropes to lift Mrs. Frisby's house and move it to a new spot. They work together to carefully transport the house, ensuring Mrs. Frisby and her children remain safe inside. With the rats' assistance, Mrs. Frisby successfully escapes the plow and finds a new home for her family.
