Read the following passage and mark the letter A, B, C, or D on your answer sheet to Indicate the correct answer to each of the questions.
There is a wide range of organisms by their population whose lives mostly depend on how they hunt or are hunted. And most living organisms have some way of protecting themselves from natural predators. Some mammals, like the platypus, carry internal toxins to transmit to predators via biting or other means, and some plants protect themselves by being poisonous. The African crested rat was originally thought to be poisonous because predators that tried to eat it often became paralyzed. But scientists have recently learned that's not actually the case.
The crested rat chews on the poisonous bark of a certain tree, and then smears the chewed-up substance onto its fur, where a strip of special quill-like hairs soaks up the poisonous mixture. Though similar to a porcupine's, the quills do differ: whereas the porcupine defends itself by poking predators, the African rat uses its quill-like hairs to deliver poison to them. When a predator comes after it, instead of running away, the rat stays put and parts its hair to reveal the strip of fur on its back where the poison is being stored. That raised strip is the first thing that receives a bite, and the poison inside disables the predator. These hair tubes are unusual. In fact, scientists do not know of another animal that uses plant poison in this way.
Scientists are puzzled that the rat doesn't appear to be affected by the poison. Because it affects heartbeat regulation, understanding how the rat can keep its heart rate regulated effectively while using the poison could help scientists develop new medicines for people with heart trouble. And they hope that those suffering from heart diseases will benefit from this.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions
Millions of people tune into the weather forecast each evening on television. Most of them imagine that the presenter does little more than arrive at the studio a few minutes before the broadcast, read the weather, and then go home. In fact, this image is far from the truth. The two-minute bulletin which we all rely on when we need to know tomorrow's weather is the result of a hard day's work by the presenter, who is actually a highlyqualified meteorologist. Every morning after arriving at the TV studios, the first task of the day is to collect the latest data from the National Meteorological Office. This office provides up-to-the-minute information about weather conditions throughout the day, both in Britain and around the world. The information is very detailed and includes predictions, satellite and radar pictures, as well as more technical data. After gathering all the relevant material from this office, the forecaster has to translate the scientific terminology and maps into images and words which viewers can easily understand. The final broadcast is then carefully planned. It is prepared in the same way as other programmes. The presenter decides what to say and in what order to say it. Next a "story board" is drawn up which lays out the script word for word. What makes a weather fore-cast more complicated than other programmes are the maps and electronic images which are required. The computer has to be programmed so that the pictures appear in the cor-rect order during the bulletin.
The time allocated for each broadcast can also alter. This is because the weather re-port is screened after the news, which can vary in length. The weather forecaster doesn't always know how much time is available, which means that he/she has to be thoroughly prepared so that the material can be adapted to the time available. Another related complication is that the weather forecast has to be a live broadcast; it cannot be pre-recorded. Live shows are very nerve-racking for the presenter because almost anything can go wrong. Perhaps the most worrying aspect for every weather fore-caster is getting the following day's predictions wrong. Unfortunately for them, this is not an unusual occurrence; the weather is not always possible to predict accurately. The weather is a national obsession in Britain, perhaps because it is so changeable. It’s the national talking point, and most people watch at least one day bulletin. It can be mortifying for a weather man or woman who has predicted rain for the morning to wake up to brilliant sunshine. This day, a weather forecaster’s job is even more complicated because they are relied upon to predict other environmental conditions. For example, in the summer the weather forecast has to include reports on ultraviolet radiation intensity to help people avoid sunburn. The job of a weather forecaster is certainly far more complicated than just pointing at a map and describing weather conditions. It's a job for professionals who can cope with stressful and demanding conditions.
What perception do most people have of weather forecasters?

Just as you designate and separate your physical workspace, you should be clear about when you’re working and when you’re not. You’ll get your best work done and be most ready to transition back to the office if you stick with your regular hours. Plus, if your role is collaborative, being on the same schedule as your coworkers makes everything much easier.
“The biggest difference between working from home and working in the office is that you are in charge of your environment and have to treat yourself like an employee,” Yurovsky says. This means holding yourself accountable, but also recognizing when enough is enough, just as a good manager might. “If you feel yourself extending your work hours because you are not doing anything in the evening...tell yourself it’s time to put work away, recharge, and start tomorrow with a fresh mind. The work will be there in the morning.”
If you live with other people, this separation is even more critical. Communicate with the people whom you live with to establish boundaries so you can cut down on distractions during the workday—and then disconnect and give the people you care about your full attention. Having a separate time and space to work will allow you to be more present in your home life.
