James Watt
1. James Watt was a Scottish inventor and mechanical engineer whose improvements to the Newcomen steam engine were fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world.
2. While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines. He realized that contemporary engine designs wasted a great deal of energy by repeatedly cooling and re-heating the cylinder. Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines. Eventually he adapted his engine to produce rotary motion, greatly broadening its use beyond pumping water.
3. Watt attempted to commercialize his invention, but experienced great financial difficulties until he entered a partnership with Matthew Boulton in 1775. The new firm of Boulton and Watt was eventually highly successful and Watt became a wealthy man. In his retirement, Watt continued to develop new inventions though none were as significant as his steam engine work.

A rover
1. A rover is a space exploration vehicle designed to move across the surface of a planet or other celestial body. Some rovers have been designed to transport members of a human spaceflight crew; others have been partially or fully autonomous robots. Rovers usually arrive at the planetary surface on a lander-style spacecraft.
2. Rovers have several advantages over stationary landers: they examine more territory and they can be directed to interesting features. If they are solar powered, they can place themselves in sunny positions to weather winter months. They can also advance the knowledge of how to perform very remote robotic vehicle control which is necessarily semi-autonomous due to the finite speed of light.
3. Their advantages over orbiting spacecraft are that they can make observations to a microscopic level and can conduct physical experimentation. Disadvantages of rovers compared to orbiters are the higher chance of failure, due to landing and other risks.
Ответьте на вопрос:
What spacecraft can be used for the purpose of cosmonauts’ transportation?
Any spacecraft can.
Stationary landers can.
Orbiting spacecraft can.
Rovers can.

Twilight
1. Twilight is the illumination that is produced by sunlight scattering in the upper atmosphere, illuminating the lower atmosphere when the Sun itself is not directly visible because it is below the horizon, so that the surface of the Earth is neither completely lit nor completely dark.
2. The further the Sun is below the horizon, the dimmer the twilight (other things such as atmospheric conditions being equal). When the Sun reaches 18 degrees below the horizon, twilight’s brightness is nearly zero. Evening twilight ends and night begins. When the Sun again reaches 18 degrees below the horizon, night ends and morning twilight begins.
3. Twilight is defined according to the solar elevation angle, which is the position of the geometric center of the sun relative to the horizon. There are three established and widely accepted subcategories of twilight: civil twilight (brightest), nautical twilight («first light»), and astronomical twilight (darkest).
Ответьте на вопрос:
What twilight is the dimmest?
It is the civil twilight.
It depends upon the solar elevation angle.
It is the nautical twilight.
It is the astronomical twilight.

Digitizing
1. The term digitizing is often used to describe the scanning of analog sources (such as printed photos or taped videos) into computers for editing, but it also can refer to audio (where sampling rate is often measured in kilohertz) and texture map transformations. In this last case, as in normal photos, sampling rate refers to the resolution of the image, often measured in pixels per inch.
2. Digitizing is the primary way of storing images in a form suitable for transmission and computer processing, whether scanned from two-dimensional analog originals or captured using an image sensor-equipped device such as a digital camera, tomographical instrument such as a CAT scanner, or acquiring precise dimensions from a real-world object, such as a car, using a 3D scanning device.
3. Digitizing is central to making digital representations of geographical features, using raster or vector images, in a geographic information system, i.e., the creation of electronic maps, either from various geographical and satellite imaging (raster) or by digitizing traditional paper maps or graphs (vector).
Основной идеей текста является …
Digitizing has become possible with the origin of computer technologies.
Digitizing is mostly used by people for the purpose of storing their data.
Digitizing information from different sources is a common thing nowadays.
Digitizing allows visual, audible, and film media to be computer processed.

Rarefaction
1. Rarefaction is the reduction of an item’s density, the opposite of compression. Like compression, which can travel in waves (sound waves, for instance), rarefaction waves also exist in nature. A common rarefaction wave is the area of low relative pressure following a shock wave.
2. Rarefaction waves expand with time (much like sea waves spread out as they reach a beach); in most gases rarefaction waves keep the same «shape» at all times throughout the wave’s movement: it is a «self-similar expansion». Each part of the wave travels at the local speed of sound, in the local medium. This expansion behaviour is in contrast to the behaviour of pressure increases, which get narrower with time, until they steepen into shock waves.
3. A natural example of rarefaction occurs in the layers of Earth’s atmosphere. Because the atmosphere has mass, most atmospheric matter is nearer to the Earth due to the Earth’s gravitation. Therefore, air at higher layers of the atmosphere is less dense, or rarefied, relative to air at lower layers. Thus rarefaction can refer either to a reduction in density over space at a single point of time, or a reduction of density over time for one particular area.

In nature rarefaction occurs in the higher layers of Earth’s atmosphere because of the Earth’s gravitation.
Rarefaction waves expand with time keeping the same «shape» at all times throughout the waves’ movement.
Rarefaction waves have certain physical properties being basically different from those of compression ones.
Like compression waves rarefaction ones also can travel in waves but the latter exist only in the area of low pressure.
