359. Ants have been around for about 100 million years and can be found in almost every land environment. They are social insects that live together in large groups or colonies. Most make their home in underground tunnels and chambers. But some ants are different. Carpenter ants carve tunnels in wood (but don`t eat it).
In the South American rain forest, many ants live in trees. And Army ants don`t build at all. They travel in big groups looking for food.
Ants communicate by touching each other with their antennae. They show other ants where food is by making a path with a chemical called a “pheromone”. This leaves a scent for the other ants to follow.
Each ant has a specific job. The queen lays eggs to populate the colony. Workers collect food, feed members of the colony, and enlarge the nest. Solders are large workers that defend the colony.
Ants are social insects that ………
a) can be found almost all over the world b) live in trees and feed on wood
c) use a “pheromone” to find food and lay eggs d) build tunnels and set their TV antennae
360. Hurricanes are the largest storm. They form over warm oceans. As the seawater evaporates into the air, the pressure drops. Winds begin to circulate. They create a huge wall of clouds and rain, wrapped around a calm center called the eye. As warm, moist air continues to feed the storm, it gets stronger. It can spread out to an area 300 miles wide and generate winds as fast as 150 miles per hour or more. Hurricanes can rip trees out by their roots. They tear roofs off buildings. The strong winds blowing toward shore create a rise in ocean water. This is called a storm surge. Combined with heavy rains, it can cause flooding and massive damage.
Which statement is true according to the text?
a) Hurricanes are strong enough to rip trees out by their roots.
b) Trees tear their roofs off the buildings.
c) It's not calm in the eye of the storm.
d) Storm surge can cause heavy rains and massive damage.
