(Global Warming Facts Quiz) The controversial issue of global warming has been widely publicized by the film An Inconvenient Truth, featuring former Vice President Al Gore. Mr. Gore and a U.N. network of scientists, the Intergovernmental Panel on Climate Change, shared the 2007 Nobel Peace Prize in recognition of “their efforts to build up and disseminate greater knowledge about man-made climate change.” Research both sides of the global warming issue online (you might want to search for phrases like “global warming skeptics”). Create a five-question multiple-choice quiz on global warming, each question having four possible answers (numbered 1—4). Be objective and try to fairly represent both sides of the issue. Next, write an application that administers the quiz, calculates the number of correct answers (zero through five) and returns a message to the user. If the user correctly answers five questions, print “Excellent”; if four, print “Very good”; if three or fewer, print “Time to brush up on your knowledge of global warming,” and include a list of some of the websites where you found your facts.
Computer-Assisted Instruction
As computer costs decline, it becomes feasible for every student, regardless of economic circumstance, to have a computer and use it in school. This creates exciting possibilities for improving the educational experience of all students worldwide as suggested by the next five exercises. [Note: Check out initiatives such as the One Laptop Per Child Project (www.laptop.org). Also, research “green” laptops—what are some key “going green” characteristics of these devices? Look into the Electronic Product Environmental Assessment Tool (www.epeat.net) which can help you assess the “greenness” of desktops, notebooks and monitors to help you decide which products to purchase.]

- Read this:Selective Service Registration Registration with the Selective Service is mandatory in America. The law states "it is the duty of every male citizen of the United States between the ages of 18 and 25, to register." The law does not require women to register. Failure to register for selective service is a crime. If found guilty, a person could be fined up to $250,000. They might also receive a sentence of five years in prison. All men over 18 should register online at the Selective Service System website (www.sss.gov). Registration can also be done at any US Post Office. It is a duty that allows for freedom in America. Explain the purpose for registering with the Selective Service System. Is this action a duty or a responsibility?arrow_forwardLife and Times of the Thunderbolt Kid by Bill Bryson: My sister and brother were considerably older than I - my sister by six years, my brother by nine - and so were effectively adults from my perspective. They were big enough to be seldom around for most of my childhood. For the first few years of my life, I shared a small bedroom with my brother. We got along fine. My brother had constant colds and allergies, and owned at least four hundred cotton handkerchiefs, which he devotedly filled with great honks and then pushed into any convenient resting place under the mattress, between sofa cushions, behind the curtains. When I was nine he left for college and a life as a journalist in New York City, never to return permanently, and I the room to myself after that. But I was still finding his handkerchiefs when I was in high school. Q/ What ?do we learn about Michael in this paragraph He was proud of his collection of handkerchiefs.

The longest chord of the ellipse is the major axis. The perpendicular chord to the major axis is the minor axis, which bisects the major axis at the center as shown in Figure 1. Ellipse is different with circle which has only one radius. There is no simple formula to calculate the exact or accurate value of perimeter of an ellipse. Therefore, we use approximation formulas to calculate the approximate value of an ellipse's perimeter. One of the approximation methods is called Ramanujan Formula as follows: p zn[3(a+b) – Г(За + b) (а + зь)| where a is the semi major axis and b is the semi minor axis of the ellipse, respectively, as shown in Figure 1. be major axis Figure 1.

- ) The number of unneeded printouts is growing eve:yyear. This practice wastes paper, electricity, storage space, and natural resources. It also contributes to pollution and landfill use. If you could do one thing to reduce the practice ofunnecessary printing, what would it be? Would you restrict paper use In offices? Would you ration paper? Would you take printers away from certain types of workers? Would you forbid the printing ofcertain types of documents (such as e-mail messages)? Are such radical actions needed?

The strangers managed to learn enough Old English to explain that they had been enjoying their favourite pastime – belting out tunes at a karaoke party – when they saw a blinding flash and heard a thunderous roar, lost consciousness, and found themselves transported back in time without any explanation. The villagers were most interested in the strangers’ wide-ranging knowledge of popular songs from the future. They understood that the strangers belonged to some sort of bard class. The villagers were also party animals, and had a feast every night. The bards agreed to come to some of the parties and sing one Billboard Top 40 song whenever they did. When they weren’t there, the villagers would sing these songs to each other, reverently, knowing that they held clues to the future of their world. The more they learned, the more they were able to share, and some were…arrow_forwardSelect the answer choice that most closely satisfies the inquiry.Programs in this category include word processors, spreadsheet editors, e-mail clients, and web browsers.arrow_forward
