The most logical and intelligent people seem to go berserk when talking about snakes. Recently a reputed scientist said with a wise look in his eyes that sand boas have two heads. The other day someone walked into my office and stated that in his village at least cobras mate with rat snakes. About other places he was not sure, he added modestly, but that was how it was in his village.

These stories about snakes are myths. Sand boas have only one head; vine snakes do not peck your eyes out; no snake will drink milk. But it is interesting to try and trace the origin of these untruths. The one about the sand boas two heads obviously exists because the short, stumpy tail of this snake looks remarkably like the head, an effective device to fool predators. Or take the one about vine snakes pecking at eyes. It was ‘probably started by a vine snake that had a bad aim, as snakes, when provoked, will bite the most prominent projection of the offender, which is usually the nose.

But the most interesting one is about snakes coming to the scene of killing to take revenge. It so happens that when injured or under stress, a snake exudes, a large quantity of musk. Musk is a powerful sex attractant, the snakes’ equivalent of after-shave lotion. So after a snake is killed, the ground around still has this smell and naturally a snake of the same species passing by will lick its lips and come to investigate. The killer of the snake, who is probably worried if the pooja he performed was adequate to liquidate the killing of a snake, sees the second snake and is convinced that it was not.

The Irula tribals have a good answer to the query about whether cobras have jewels in their heads; “If they did, we wouldn’t be snake catchers, we would be rajas!”

Among Nature’s most intriguing phenomena are the partnerships formed by any different species. The name used for these relationships, Symbiosis, comes from Greek meaning "living together". Not all symbiotic relationships are the same. There are some called commensal relationships, in which one partner gains a benefit while the other gains little or none but is not harmed. One example is the relationship between two types of fish remoras and sharks. The remora, which is long and often striped, attaches itself to a shark (sometimes to another type of fish or a whale), using a sucker on its head. When the shark makes a kill, the hitchhiker briefly detaches itself to feed on the scraps. Another type of symbiotic relationship is parasitism, in which one partner benefits at the expense of others. Ticks and tapeworms are among familiar parasites. 

The third type of symbiotic relationship, called mutualism, is a true partnership in which both partners benefit. The relationship may be limited as when zebras and wild best graze together on the vast African grasslands. Each species can survive on its own, but together their chances of detecting predators are improved because each contributes a specially keen sense. (Zebras have the better eyesight;  wild beast, hearing and sense of smell). In a few cases partners are so interdependent that one cannot survive without the other. Most mutualistic relationships probably lie some where in between

Commensal relationship is a type of symbiosis in which the relationship is beneficial 

Read the following passage and answer the questions given after it.

The Celts who lived in Britain before the Roman invasion of 43 AD could be said to have created the first towns. Celts in southern England lived in hill forts, which were quite large settlements. (Some probably had thousands of inhabitants). They were places of trade, where people bought and sold goods and also places where craftsmen worked. The Romans called them oppida.

However, the Romans created the first settlements that were undoubtedly towns. Roman towns were usually laid out in a grid pattern. In the centre was the forum or market place. It was lined with public buildings. Life in Roman towns was highly civilized with public baths and temples.

From the 5th century Angles, Saxons and Jutes invaded England. At first, the invaders avoided living in towns. However, as trade grew some towns grew up. London revived by the 7th century (although the Saxon town was, at first, outside the walls of the old Roman town). Southampton was founded at the end of the 7th century. Hereford was founded in the 8th century. Furthermore, Ipswich grew up in the 8th century and York revived. However, towns were rare in Saxon England until the late 9th century. At that time, Alfred the Great created a network of fortified settlements across his kingdom called ‘burhs’. In the event of a Danish attack, men could gather in the local burh. However, burhs were more than forts. They were also market towns. Some burhs were started from scratch but many were created out of the ruins of old Roman towns. Places like Winchester rose, phoenix-like, from the ashes of history.

The thing that would strike us most about medieval towns would be their small size. Winchester, the capital of England, probably had about 8,000 people. At that time a 'large' town, like Lincoln or Dublin had about 4,000 or 5,000 inhabitants and a 'medium sized' town, like Colchester had about 2,500 people. Many towns were much smaller. However, during the 12th and 13th centuries most towns grew much larger. Furthermore, many new towns were created across Britain. Trade and commerce were increasing and there was a need for new towns. Some were created from existing villages but some were created from scratch. In those days you could create a town simply by starting a market. There were few shops so if you wished to buy or sell anything you had to go to a market. Once one was up and running, craftsmen and merchants would come to live in the area and a town would grow.

Match the words with their meaning.

a. founded 1. protected

b. declined 2. created

c. fortified 3. dwindled

Read the passage given below and answer the questions that follow.

It is well accorded that COVID-19 extracts a huge toll on the mental health of patients and leaves behind a slew of neurological sequelae in its wake. However, what is alarming is the wide gamut of mental and neurological disorders seen even in those with milder symptoms. Such patients frequently reported being anxious, depressed and having difficulty in sleeping. A higher incidence of frank psychosis manifesting as disorganization of thought processes and personality disorders was also reported. Many survivors of COVID19 had to battle substance abuse in its immediate aftermath. There was a steep increase in the amount of alcohol consumed by regular drinkers. Persons who had stopped smoking and consuming alcohol resumed their habit in disconcerting numbers.

The occurrence of neurodegenerative disorders like Parkinsonism is concerning as this would bring longterm disability in the form of impaired mobility and memory decline. It has been hypothesized that the causative mechanism for many of the neurological conditions due to COVID-19 may be the direct invasion of the nervous system by the virus, an increased tendency to blood clotting or an exaggerated immune response by the body. Various other factors like pre-existing psychiatric illness, prolonged quarantine, perceived lack of organizational support, and social stigma are risk factors. Anxiety, Nervousness, and Posttraumatic stress disorder are often fuelled by fear of infecting other family members, physical distancing, loneliness, and ________ at home in cramped quarters.

The pandemic has radically transformed the way businesses function and services delivered. Remote working disrupts a healthy-work life balance. Face to face contact and human interactions which were considered so essential for emotional well-being has taken a backseat. Lack of comforting physical contact like shaking hands and hugging friends is stressful and disconcerting. Online classes and home-schooling have placed a gargantuan burden both on students and parents. Lack of access to reliable computer hardware and spotty internet connections, particularly in rural areas and in the economically backward have created a new class divide. Children have been deprived of co-curricular activities, participation in group events and sports which is essential for their holistic development. Mental stress and fatigue have increased manyfold due to the rigours imposed by virtual learning.

What is the synonym of the word gargantuan mentioned in the passage?

There is a general consensus that ‘International Understanding’ need to be taught as a separate subject at the school stage as that would add to the curricular load which is already too heavy. Instead it should be woven into the curriculum and the numerous opportunities that present themselves while teaching normal school subjects may be intelligently and imaginatively used by the teacher to promote International Understanding.

The school subjects which can be most profitably used for this purpose are History, Geography, Civics, Economics, Sociology, Political Science, Social Sciences, Languages as well as Physical and Life Sciences. However, at the higher education level, international education can be prescribed as a separate subject of study. In fact, the present situation in India broadly conforms to this consensus so far as the school stage is concerned.

At the under-graduate and the post-graduate levels, courses of study in subjects like History, Geography, Economics, Political Science, International Relations, International Law and International Organization have been prescribed by most of the universities and these contain content which has a direct or indirect bearing on promoting UNESCO ideals

Long ago men spent most of their time looking for food. They ate anything they could find. Some lived mostly on plants. They ate the fruit, stems, and leaves of some plants and the roots of others. When food was scarce, they ate the bark of trees. If they were lucky, they would find a bird’s nest with eggs. People who lived near the water ate fish or anything that washed ashore, even rotten whales. Some people also ate insects and small animals like lizards that were easy to kill.

Later, men learned to make weapons. With weapons, they could kill larger animals for meat. These early people had big appetites. If they killed an animal, they would drink the blood, eat the meat, and chew the bones. When they finished the meal, there was nothing left.

At first men wandered from place to place to find their food. But when they began to grow plants, they stayed in one place and ate what they could grow. They tamed animals, trained them to work, and killed them for meat. Life was a little better then, but there was still not much variety in their meals. Day after day people ate the same food.

Gradually men began to travel greater distances. The explorers who sailed unknown seas found new lands. And in these lands they found new food and spices and took them back home.

The Portuguese who sailed around the stormy Cape of Good Hope to reach China took back “Chinese apples”, the fruit we call oranges today. Later, Portuguese colonists carried orange seeds to Brazil. From Brazil oranges were brought to California, the first place to grow oranges in the United States. Peaches and melons also came from China. So did a new drink, tea.

What did men eat if there was shortage of food?
