Read the passage and answer the question that follow.


(1) Sleep, considered a luxury by many, is essential for a person's wellbeing. Researchers have found that insufficient sleep increases the risk of developing severe medical conditions, such as obesity, diabetes, and cardiovascular disease. Now, a new study by Boston's Massachusetts Institute of Technology (MIT) has found that getting sufficient sleep is also the key to improve academic performance.
(2) They were not trying to find the correlation between sleep and grades when Fitbits to the 100 students were handed out. Instead, the professor hoped the popular wrist-worn device which, tracks a person's activity 24/7, would show a connection between physical exercise and academic achievement. As part of the research, a quarter of the participants were enrolled in an intense fitness class specially created for the study. After the semester ended, the researchers carefully analyzed the data. Much to their surprise, they found no measurable difference in test performance between the group that had been physically active and the group that had been sedentary.
(3) However, the study yielded a surprising insight. As the researchers were parsing through the large amount of data, they noticed an interesting trend emerging from the participants' sleep patterns. There was a straight-line relationship between the average amount of sleep a student got and his or her grades on the 11 quizzes, three midterms, and the final exam administered during the semester. Even more interesting, it was also not sufficient for students to just head to bed early the night before a test. We've heard the phrase Get a good night's sleep, you've got a big day tomorrow.' However, it turns out this does not correlate at all with test performance. Instead, it's the sleep you get during the days when learning is happening that matter most.
(4) The time students went to bed each night was similarly important. Those who went to bed in the early hours of the morning performed poorly, even if the total sleep time was the same as a higher-performing student. So, when you go to bed matters. If you get a certain amount of sleep — let's say 9 hours — no matter when you get that sleep, as long as it's before certain times. Say you go to bed between 10pm and 1am, your performance is the same but if you go to bed after two in the morning, your performance starts to go down even if you get the same nine hours so you should probably be asleep before then. So, quantity isn't everything. The research does not prove that sleep is the only factor that helps improve academic performance. However, the lead researcher says the results are a strong indication that sleep really matters. So, with teens estimated to need around 9 to 10 hours sleep a day and the average school goer getting up at 7 am, the results may suggest a bedtime of 9 or 10 at night. This can be shifted somewhat at the weekend if the student still gets their correct number of hours and can sleep in long enough to ensure the suggested amount of time and it also doesn't factor in having an afternoon sleep.

Read the passage and answer the question that follow.

Yoga is a practice that has been practised for centuries and is thought to have originated in India. It is a spiritual discipline that teaches a person to become more aware of his/her body, mind, and spirit.

In the beginning, it was used in the East to promote meditation and to control the mind and the body, but now there are various traditions of yoga being practised around the world. There are many different styles of yoga, which are practised in different countries.

One of the core areas of practice is breathing. This allows the learner to connect with the breath. By taking care of the mind and the body through breathing techniques, the practitioners are able to achieve heightened levels of awareness.

Practitioners are often encouraged to take a meditation break every thirty minutes. Practitioners will focus on their breathing and use these breaks to connect with their spirit.

Some practitioners may also practice ‘Japa’, which is a series of chanting and calling of the mantras, where participants focus on the messages of the mantras. The mantras are meant to help bring one to a meditative state, which can then be used to reach higher levels of spiritual awareness.

The process of performing this kind of meditation is called Kundalini, which literally means serpent power. Kundalini, along with Pranayama, will help prepare the body for higher levels of spiritual awareness. When practising Kundalini meditation, practitioners will experience physical sensations in both the top and bottom of the spine.

Another meditation that is practised to reach the highest levels of Kundalini is named Sukhasana. This means to hold back the throat, but not the breath. The goal of this type of meditation is to force the learner to slow down, which allows for deeper levels of relaxation and meditation.

We have all heard of meditation and the process of consciousness in the state of being quiet. Yogic practitioners may have their mind open, but the very essence of them is left behind as they may practice a state of oneness with the universe. They may learn to communicate and express themselves through this state of oneness.

When we choose to enter the natural state of our body, our mind, and spirit, they naturally merge together. As the breath becomes controlled and the mind moves to a meditative state, the body is inspired to move into a meditative state. This part of the practice is known as Asana.

While practising yoga there is a natural balancing effect that happens. It allows the body to work at its best level and it helps the mind to work at its best level. This is the basis for getting the most out of your yoga workout. There are many benefits of yoga workouts. It can be used to prepare for specific therapies. However, when you combine all the above elements, you have a very effective way to get your body ready for those higher levels of therapy.

Read the passage and answer the questions that follow.
The challenge of climate change is global, and it demands action on an international scale, such as the Paris Agreement. But a large part of the solution must be local, involving all of us in the way energy is produced and consumed. Very recently, there was a decision made that has allowed the Argentina population to now generate their own energy through clean and unconventional sources and add surpluses into the public grid. This is an important novelty in a country beginning a slow and difficult process, with a still uncertain end, to replace fossil fuels. A new law was born with the aim of increasing the generation and addition to the grid of clean energy by many small nearby sources, citizens and other private sectors, in what is known as distributed, dispersed or decentralised generation.
Argentina has had a hard time shifting to renewable power sources. They still represent a very small share of the electric grid, which is made up of 64 percent fossil fuel power plants; fueled by oil or gas. It is a global issue and other countries, such as the UK could also do more to encourage citizen generated electricity. In the UK, more people could support the energy transition, and share in the benefits, by storing power in batteries, electric vehicles and smart boilers. This enables the grid to draw power when it's cheap and plentiful, and temporarily lighten the load if there's a peak in demand. Here, since 2009, the price of solar panels has fallen by 80% and wind turbines by 40%. And it won't stop there. Renewable energies are becoming competitive with fossil fuels and new nuclear, but still out of reach of many of the regular citizens.
Renewable energies and supporting technologies, like storage, are advancing in leaps and bounds. The old energy companies have been sluggish in catching up so, although there is the ability to produce more electricity via renewable, investment is still being made in gas and nuclear power. With the right government policies in the UK there could be great potential for citizen-owned energy. Take Germany and Denmark as examples in how successful citizen-generated electricity has become. Recently, Germany produced so much electric power that prices were actually negative. As in, customers got paid to use the electrical system. However, the average overall percentage produced by renewables last year was 33%. Neighbouring Denmark already sometimes produces more renewable energy than the nation's citizens consume on a more regular basis with 40% of the national electricity being supplied by wind. They are currently 90% self-sufficient for their energy needs.
Electricity generation in Denmark has changed fundamentally over the past two decades and Denmark has a long tradition of setting ambitious national energy targets. By 2050, Denmark aims to be a lowcarbon society independent of fossil fuels. All in all, Europe is performing well in its organisation of renewables. In 2011, renewables created 21.7% of the EU's power. After three years, this figure has achieved 27.5% and is expected to grow to 50% by 2030. The EU's underlying endeavours in advancing the use of renewables encouraged this. Proceeded by the development, which brought down sustainable costs, renewables have now moved toward becoming cost-focused, and even sometimes significantly less expensive than fossil fuels.
