Read the following article and answer the question. Article: Inventor, physicist, surveyor, astronomer, biologist, artist... Robert Hooke was all there and more. Some say he was the greatest experimental scientist of the 17th century. In the course of his work, he cooperated with famous men of science like Isaac Newton, and the great architect, Christopher Wren. Hooke's early education began at home, under the guidance of his father. He entered Westminster School at the age of 13, and from there went to Oxford, where he came in contact with some of the best scientists in England. Hooke impressed them with his skills at designing experiments and inventing instruments. In 1662, at he age of 28, he was named Curator of Experiments at the newly formed Royal Society of London- meaning that he was responsible for demonstrating new experiments at the society's weekly meeting. Hooke accepted the job, even though he knew that the society had no money to pay him! Watching living things through a microscope was one of his favourite pastimes . He invented a compound microscope for this purpose. One day while observing a cork under a microscope, he saw honeycomb-like structures. There were cells -the smallest units of life. In fact, it was Hooke who invented the term "cell" as the boxlike cells of the cork reminded him of the cells of a monastery . Another achievement of Hooke's was his book Micrographia, which introduced the enormous potential of the microscope. It contains fascinating drawings of the thing he saw under the microscope. The book also includes, among other things, ideas on gravity, light and combustion that may have helped scientists like Newton when they were developing their own theories on these phenomena . Hooke made valuable contributions to astronomy too. A crater on the moon is named after him in honour of his services to this branch of science. Question: Which of the following is true according to the text? Answer:
OPTIONS:
- Hooke went to Oxford in 1645.
- Hooke was well paid in the Royal Society of London.
- Hooke made a contribution to medicine.
- Hooke's book Micrographia may have helped Newton.

Answer: Hooke's book Micrographia may have helped Newton.
