From the beginning, not so many people realized the danger of the Coronavirus so they did not do much to protect themselves.
Read the text and choose the best answer to fill in the blanks.
Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus. Most people infected the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment. Older people, and with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more to develop serious illness,
The best way to prevent and slow down transmission is to be well informed about the COVID-19 Virus, the disease causes and how it spreads. Protect yourself and others from infection by washing your hands or using an alcohol based rub frequently and not touching your face.
The COVID-19 Virus spreads primarily through droplets of saliva or discharge from the nose when an infected person coughs or sneezes, so it's important that you also respiratory etiquette (for example, by coughing into a feed elbow).
At this time, there are no specific vaccines or treatments for COVID-19. there are many ongoing clinical trials evaluating potential treatments, WHO will continue to provide updated information as soon as clinical findings become available.

Nanotechnology refers to the creation and use of materials or devices at extremely small scales. These materials or devices fall in the range of 1 to 100 nanometers (nm). One nm is equal to one-billionth of a meter (0.000000001 m), which is about 50,000 times smaller than the diameter of a human hair. Scientists refer to the dimensional range of 1 to 100 nm as the nanoscale, and materials at this scale are called nanocrystals or nanomaterials.
The nanoscale is unique because nothing solid can be made any smaller. It is also unique because many of the mechanisms of the biological and physical world operate on length scales from 0.1 to 100 nm. At these dimensions, materials exhibit different physical properties; thus scientists expect that many novel effects at the nanoscale will be discovered and used for breakthrough technologies.
A number of important breakthroughs have already occurred in nanotechnology. These developments are found in products used throughout the world. Some examples are catalytic converters in automobiles that help remove air pollutants, devices in computers that read from and write to the hard disk, certain sunscreens and cosmetics that transparently block harmful radiation from the Sun, and special coatings for sports clothes and gear that help improve the gear and possibly enhance the athlete's performance. Still, many scientists, engineers, and technologists believe they have only scratched the surface of nanotechnology's potential.
Nanotechnology is in its infancy, and no one can predict with accuracy what will result from the full flowering of the field over the next several decades. Many scientists believe it can be said with confidence, however, that nanotechnology will have a major impact on medicine and health care; energy production and conservation; environmental cleanup and protection; electronics, computers, and sensors, and world security and defense.

Sensing phantom phone vibrations is a strangely common experience. Around 80% of us have imagined a phone vibrating in our pockets when it's actually completely still. Almost 30% of us have also heard non-existent ringing. Are these hallucinations ominous signs of impending madness caused by digital culture?
In fact, phantom vibrations and ringing illustrate a fundamental principle in psychology. It's an example of a perceptual system, just like a fire alarm, an automatic door, or a daffodil bulb that must decide when spring has truly started. Your brain has to make a perceptual judgment about whether the phone in your pocket is really vibrating. And, analogous to a daffodil bulb on a warm February morning, it has to decide whether the incoming signals from the skin near your pocket Indicate a true change in the world.
Psychologists use a concept called Signal Detection Theory to guide their thinking about the problem of perceptual judgments. Analyzing the example of phone vibrations, we can see how this theory explains why they are a common and unavoidable part of healthy mental function. When your phone is in your pocket, the world is in one of two possible states: the phone is either ringing or not. You also have two possible states of mind: the judgment that the phone is ringing, or the judgment that it isn’t. Obviously, you'd like to match these states in the correct way. True vibrations should go with "it's ringing", and no vibrations should go with "it's not ringing". Signal detection theory calls these faithful matches a "hit" and a "correct rejection", respectively.
But there are two other possible combinations: you could mismatch true vibrations with "it's not ringing" (a "miss"); or mismatch the absence of vibrations with “it’s ringing" (a “false alarm”). This second kind of mismatch is what's going on when you imagine a phantom phone vibration.
For situations where easy judgments can be made, such as deciding if someone says your name in a quiet room, you will probably make perfect matches every time. But when judgments are more difficult - if you have to decide whether someone says your name in a noisy room, or have to evaluate something you're not skilled at - mismatches will occasionally happen. And these mistakes will be either misses or false alarms.
