Eratosthenes was born about 2,240 years 
ago. He studied in the great centers of 
learning at the time. He became the director 
of the Library of Alexandria. He was a very 
successful scientist. He made many 
important discoveries. For example, he 
correctly measured the tilt of Earth’s axis. In 
math, he developed a system for finding 
prime numbers. He also studied the 
movement of the planets. And he suggested 
the use of a leap year every four years. 
According to him, this would keep the 
calendar correct. 
However, his greatest discovery was his 
ability to measure the distance around the 
center of Earth. He knew that Earth was 
round. He recognized this fact because he had 
seen the curved shadow of Earth during an 
eclipse. He knew that the sun cast no shadow 
on a deep well in a neighboring city. This was 
at exactly noon on the first day of summer. 
Trained men measured the exact distance 
between the two cities. The librarian 
measured the arc of a circle formed by the two 
cities at 7.2 degrees. He then divided the 7.2 
degrees into the 360 degrees of a circle. He 
realized that the distance around Earth was 
fifty times the distance between the two 
cities. In today’s terms, that would be 25,000 
miles. Little did he know, his estimate would 
be proven correct in modern times using exact 
measuring tools.

Read the text. Then choose the correct answer 
for each question below (23-26). 
Substance can be a liquid, a solid, or gas. 
Water can change into three forms. It only 
depends on water temperature. When water 
is a liquid, we drink it. When water is cold, it 
is a solid, such as ice or snow. When water is 
a gas, we call it water vapour. When water 
boils, it changes into vapour or steam. The 
water vapour is collected in clouds. Then it 
falls to the ground as rain or snow. Some 
people think that the amount of water 
changes when the water moves from one state 
to another. Actually, the amount of water 
always stays the same, no matter which state 
the water is in. People are tricked because of 
the amount of space which water uses in its 
different forms. Solid form takes up more 
space than liquid form. Vapour form takes up 
the least amount of space.
