Problem: In context of spaceflight, a satellite is an artificial object which has been intentionally placed into orbit. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as Earth's Moon.

In 1957 the Soviet Union launched the world's first artificial satellite, Sputnik 1. Since then, about 6,600 satellites from more than 40 countries have been launched. According to a 2013 estimate, 3,600 remained in orbit. Of those, about 1,000 were operational; while the rest have lived out their useful lives and became space debris. Approximately 500 operational satellites are in low-Earth orbit, 50 are in medium-Earth orbit (at 20,000km), and the rest are in geostationary orbit (at 36,000km). A few large satellites have been launched in parts and assembled in orbit. Over a dozen space probes have been placed into orbit around other bodies and become artificial satellites to the Moon, Mercury, Venus, Mars, Jupiter, Saturn, a few asteroids, and the Sun.

Satellites are used for many purposes. Common types include military and civilian Earth observation satellites, communications satellites, navigation satellites, weather satellites, and space telescopes. Space stations and human spacecraft in orbit are also satellites. Satellite orbits vary greatly, depending on the purpose of the satellite, and are classified in a number of ways. Well-known (overlapping) classes include low Earth orbit, polar orbit, and geostationary orbit.

Problem: (CNN) -- The height of luxury -- or a vulgar monstrosity?

To its owner, this 15-meter, Lamborghini-inspired speedboat is the apex of nautical engineering. A sleek, innovative, gutsy vessel worthy of its $1.1 million price tag.

But others disagree.

When Gino Gargiulo turned up at the Miami Boat Show with his banana-yellow beauties in tow -- the boat and the $750,000 car it resembles -- a small crowd quickly gathered around.

"This is the best boat you can buy -- it's the Lamborghini of boats," says the 48-year-old automobile and restaurant mogul from Miami, Florida.

"The response we've had ... letters, emails. If you do a Google search today there are 14,000 pages on it already -- and the boat's never even been in the water."

However, not everyone is impressed by the idea of a high-performance sports car dressed up as a superyacht.

To Quentin Willson, former presenter of BBC TV show "Top Gear," the Lamborghini boat is a tasteless display of wealth that screams: "I'm rich and bored."

Willson quickly moves into fourth gear with his analysis.

"And that's really sad. Anybody who's got that amount of money that they need to go and commission a special boat to keep them entertained -- I think it's nuts," he says.

"The key with these people is they want to be different, and they want to be separate, and they want to be distinctive -- and that impulse throws good taste, and reason, and rationale out the window."

Problem: New Brunswick, New Jersey (CNN) -- The man Tyler Clementi was intimate with just days before he committed suicide took the stand Friday, telling jurors that he had noticed a web camera aimed at Clementi's bed.

The witness, who prosecutors named only as "M.B." to protect his identity, testified during the sixth day of the trial of a former Rutgers University student, Dharun Ravi.

Ravi is accused of spying on and intimidating Clementi, his former university roommate, because he was gay.

M.B., 32, testified Friday that he first met Clementi on an internet social networking site for gay men and that they eventually met in the student's dorm room three times. The two conversed online, exchanged text messages and later had sex.

At one point when they were together in the dorm room, M.B. glanced over at Ravi's desk and saw "a camera lens pointed at (Clementi's) bed."

He also testified that he had briefly met Ravi while visiting Clementi. Ravi on one occasion allegedly left the room and came back, "walked to his desk, shuffled around a bit and then walked out."

M.B. testified that on September 19, 2010, he drove to meet Clementi at his building, three days after the first visit. When he left, M.B. said he saw about five people milling around the hallway who seemed to be looking at him.

"They didn't say anything," he said. But they were looking at him in a way that made him wonder why they were staring, he said. "But as I was a guest in their building, I just brushed it off."

Problem: Adult contemporary music (AC) is a style of music, ranging from 1960s vocal and 1970s soft rock music to predominantly ballad-heavy music of the present day, with varying degrees of easy listening, pop, soul, rhythm and blues, quiet storm, and rock influence. Adult contemporary is rather a continuation of the easy listening and soft rock style that became popular in the 1960s and 1970s with some adjustments that reflect the evolution of pop/rock music.

Adult contemporary tends to have lush, soothing and highly polished qualities where emphasis on melody and harmonies is accentuated. It is usually melodic enough to get a listener's attention, and is inoffensive and pleasurable enough to work well as background music. Like most of pop music, its songs tend to be written in a basic format employing a versechorus structure.

Adult contemporary is heavy on romantic sentimental ballads which mostly use acoustic instruments (though bass guitar is usually used) such as acoustic guitars, pianos, saxophones, and sometimes an orchestral set. The electric guitars are normally faint and high-pitched. However, recent adult contemporary music may usually feature synthesizers (and other electronics, such as drum machines).
1. What era does Adult contemporary cover?
Answer:
1. The 1960s and 1970s.
