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.

Choose the statement that is true according to the passage.

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.

When was Southampton founded?

Directions: Read the passage carefully and answer the questions that follow:

Over the years, there have been many cases of news breaking about plastic toys and their containment of toxins. In addition to the harmful ingredients that can be found in plastic, we also have to take into account the effect on the environment that plastic usage has.

The internet is flooding with ways to reduce plastic usage and people are more aware of the need to cut down on this. Still, it’s difficult to change behaviors and somehow parents easily end up with a great number of plastic toys at home. This happens partly because you receive gifts from friends and family, and to some extent because kids prefer bright-colored plastic toys more than bland, wooden ones.

Not all toys contain toxins, but they can be found in some cases. Toys that have toxins in them are hazardous to children mainly because of their tendency to swallow and chew on the toys, which can result in the toxins being absorbed by the body. When it comes to young children, even the smallest amounts of toxins can affect their health.

The toxins can either be found in the plastic itself or they can be included in the pigments used to color toys and make them more attractive to children.

Although there are EU regulations for which toxins may or may not be included in toys, there are products that can slip through the cracks. Plastic toys may, for example, be made of, or contain, polyvinyl chloride (PVC), which contains lead and cadmium — both toxins that are harmful to children.

The CE mark is supposed to be a sign of quality. The toys have gone through and followed the rigorous EU standards for toys. The EU notes, though, that this marking should only be seen as an indication, as it has been misused due to counterfeiting.

As goes for all plastic, plastic toys are made using fossil fuels, and therefore the production of them contributes to the environmental crisis at hand. Therefore, it would be a good idea to minimize the buying of new plastic toys.

Environmentalists have raised awareness around the fact that plastic toys are a big part of the plastic that ends up in landfills and oceans, which adds to the ongoing issue of plastic pollution. According to a survey done by the British Heart Foundation, 1 in 3 parents admits to having thrown away toys in working conditions. Considering that 90 percent of toys are in some way made of plastic, that quickly adds up to a lot of plastic waste.

In conclusion, yes plastic toys are damaging to the environment. Even though they have a longer life cycle than single-use plastic, they will at some point end up in a landfill — or worse in the sea as non-recyclable waste. But how can we stop this issue?

Buy sustainable and non-plastic toys if you do want to buy new toys, try to aim for toys made from more sustainable materials. There are plenty of retailers that focus on environmentally-friendly toys. For example, smaller e-commerce sites like Frida & Fritiof focus on providing non-toxic and eco-labeled toys. If you do want to buy plastic toys, try to minimize the environmental impact by buying them second-hand. There are plenty of charity shops where you can buy toys, but if that is not for you, you can use a site like eBay or any other online marketplace to find second-hand toys. Be aware, though, when buying second-hand toys that security standards might have been updated since they were produced, so double-check that they are up to today’s standards.

What is the internet flooding with?
