Read this excerpt from "Why Are They Called Black Holes?"

Scientists cannot see gravity, but they can see its effects. The gravity of a black hole will swallow matter and light that drift close enough to it. Some light passing by a black hole can be far enough away that it could avoid being sucked in, but the path of the light would still be bent by gravity.

Astronomers can observe these effects. For example, when a black hole passes through a cloud of dust, it pulls the dust inside it like a big gravity-powered vacuum cleaner. When a star passes too close to a black hole, the black hole pulls it in and breaks up the star, spewing giant flashes of high energy called gamma-ray bursts. And when scientists see light bending even though there is no visible matter nearby, they have evidence that there is an invisible black hole.

What must be present for scientists to detect black holes?

a cloud of dust
a gamma ray burst
the loss of a star
the force of gravity

The answer is option B) a gamma-ray burst.

The gas molecules in the disk swirl around the black hole so fast that they heat up and emit X-rays. These X-rays can be detected from Earth. Black holes can also be detected by watching for motions of stars near the black hole.

The first black hole ever discovered was Cygnus X-1, located within the Milky Way in the constellation of Cygnus, the Swan. Astronomers saw the first signs of the black hole in 1964 when a sounding rocket detected celestial sources of X-rays according to NASA.

In the investigation both of the orthography and signification of words, their ETYMOLOGY was necessarily to be considered, and they were therefore to be divided into primitives and derivatives. A primitive word, is that which can be traced no further to any English root; thus circumspect, circumvent, circumstance, delude, concave and complicate, though compounds in the Latin, are to us primitives. –Preface to A Dictionary of the English Language, Samuel Johnson What is the connotation of the word primitives as it is used in the passage? Based on the word’s connotation, what is the meaning of primitives as it is used in the passage?

Reread paragraph 4 which of these is evidence that helps support the authors point

Fry remembered a curious adhesive – a strong and yet easily removed “unglue”– that Spencer Silver, another 3M researcher, had come upon several years earlier. . . . Silver felt the unusual adhesive might have some commercial value, and so he demonstrated it to various colleagues, including Fry. At the time, no one had come up with a use for it, and so the formula for the weak adhesive was filed away – until the Monday morning when Fry came to work with the idea of making sticky bookmarks that could also be removed without damaging the book. —The Evolution of Useful Things, Henry Petroski Why was Spencer Silver's work an essential part of Fry's invention? He worked alongside Fry on the sticky notes. He convinced other people to believe in Fry's invention. He told Fry about the "unglue" that he had discovered. He came up with a commercial use for the "unglue."

text:was born in the countryside and lived in the village. But a few years ago, our family moved into the city. I study at school in the city, but I spend every summer in the countryside at my grandparents. My grandparents’ farm is located far away from the noisy city.

I like spending my vacations in the countryside because life in the village is very quiet and even relaxed. I know exactly what I need to do every day and that gives me an opportunity to plan my day and enjoy my free time.

What I like most about living in the countryside is that we are close to nature. We can grow our own fruit and vegetables in the garden. My grandparents also cultivate the land for farming purposes, they grow some crops there and look after domestic animals.

There are many more things people can do in the countryside. As for me, I like to walk in the fields and forest. When I walk, I enjoy bird watching and bird singing. And what is more I can take a deep breath as air is not polluted in the countryside. But there are more places for walking and bike riding. There is a possibility to enjoy swimming and fishing in the river nearby. I love my home village a lot!
