355. Paper and printing were first invented in China. Paper came into Europe through the Muslim world. It was common by the 14th century. Johann Gutenberg of Germany perfected printing in the 1450s. Once books no longer had to be copied by hand, they became less expensive. Reading became more common. At first, books were still not easy to make and not cheap. Each letter was on a separate piece of type. A typesetter had to put each letter into place individually. Once all the letters for the page were in place, they were covered with ink and printed. This was done one page at a time by hand on a press until the 19th century.
What does the word “they” in the passage refer to?
a) letters b) printers c) books d) typesetters
356. 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.
According to the text, all of the following statements are FALSE, EXCEPT:
a) the job of the queen ant is to reproduce.
b) Army ants` job is to guard the colony.
c) Ants all over the world live in underground tunnels and chambers.
d) Soldiers are engaged in enlarging the nest
