1. Read the passage and answer the questions:
Students tend to lose their pencils, break them without thinking, and find all sorts of non-writing uses
for them. The pencil in your hand is one of the most remarkable and useful tools in the world. A man
named Friedrich Staedtler invented the modern "Jead" pencil in about 1622 in Germany. He was the
first person to mass-produce them. Staedtler did not use lead, and there is no lead in your pencil.
However, some pencils did use lead until the early twentieth century. Lead will make a mark, but it is
toxic and not safe to use either in the hands or around the face and mouth where many pencils
sometimes stray. Staedtler used black graphite, a soft form of carbon. Graphite is still used today. It is
mixed with clay and wax and heated to high temperatures. The modern pencil is a superb piece of
technology. The pencil is less messy than ink, can be easily erased, and makes clear, dark, smooth, and
smudge-free lines. The modern pencil can produce a continuous line twenty-two miles long. That's a
distance of 116,160 foot-long rulers laid end to end. Enjoy your pencil. For a few cents each, it is a
remarkable bargain.
Mention two improper ways in which students make use of pencils.
Lead is rarely used to make pencils. Why so?
Of what material are pencils made of?
Why can we consider the modern pencil to be a superb piece of technology?
The modern pencil can produce something fantastic. What is it?

1) Poisonous
ii) Removed something completely=
F.

Answer:
Lead is rarely used because it is toxic when put in the mouth.

Pencils are considered to be a superb price of technology because they are smooth to write, the marks can be erased and we can write a twenty foot line with the pencil.
It can produce a 20 foot long line.
Poisonous= Which causes harm to an organism when it comes to contact.
