Question

16. Write a letter to your elder brother describing the college annual
day celebrations in your polytechnic.
17. Read the following passage and make notes :
There are four important types of heart diseases. Firstly,
congenital heart disease, which is present at birth; an example of
this is the so-called blue baby'. It accounts for 2% of all heart
diseases. The second type, rheumatic, is quite common in some
30–40% of all heart cases. It is caused by an infection of the throat
which if untreated causes damage to the heart. The symptoms are
a chronic sore throat, painful joints and high fever. This disease
is widespread in many developing countries due to poor living
conditions and overcrowding.
High blood pressure is also an important cause of heart disease,
of the third type-hypersensitive, and accounts for 15 to 25% of
all heart cases. It is believed that among other factors such as
stress and smoking, a higher salt intake in the diet leads to blood
pressure.
Degenerative heart disease, commonly known as ischaemic heart
disease is the cause of heart attacks, and is one of the most
important health problems among adults throughout the world.
Ischaemic heart disease is due to blocking of two blood vessels
which supply blood to the heart muscle. At birth they are wide
open but in a diseased state one or more of these vessels is
completely blocked, leading to defective blood supply to various
points of the heart. This results in well-known symptom of pain
on emotional or physical stress called 'angina'. What causes this,
is the laying down of fatty substance called cholesterol in the
walls of the artery, which gradually blocks the vessel and may
close it completely.
18, Read the following passage and answer the questions that follow :
There was a Guru who had mastered all the Vedas. One day when
he was teaching the Vedas to his disciples, a cat started moving
around. This did not disturb the Guru, but was a distraction to
some of his disciples. So the Guru instructed his disciples to get
hold of the cat and tie it to a pillar. As the nuisance recurred on
the following days, the cat was regularly tethered to the pillar
before the Guru began the teaching.
Some years later, the Guru died. One of his disciples became the
new head. The practice of tethering the cat to the pillar continued.
