Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: "The price of books for our students is just getting higher and higher and,combined with the rising cost of tuition,it's killing these students,"said Peter Jason,a college professor."Remember,students are one of the poorest groups of people in America.Almost half of them have at least one part-time job.In fact,one of my students has three jobs.And she still manages to have high scores and go to school full-time." Textbook prices are traditionally high.Adding to that problem,many college teachers change textbooks year after year;they either upgrade to a new edition or switch to an entirely different textbook.This further hurts students because if an instructor no longer uses a particular textbook,that book has no resale value. Dr.Jason decided to make lire a little easier and a lot cheaper for his students by writing his own book on public speaking."Many books have an increased price because of CD-ROMs,lots of color photographs and pictures.I talked to my students,and many of them,like me,prefer to keep things simple! So,a few years ago,I wrote my own textbook.Compared to most other public speaking books,mine is half the number of pages,and one-third the price.That is,$30 instead of $90.When I wrote a second edition last year,students only had to buy the 35 new pages, For only $7.00,they had almost a new book. Now my loose-leaf textbook enjoys great popularity among the students.Maybe in the future more writers and publishers will try it." Options: A About 7 dollars. B About 30 dollars. C About 37 dollars. D About 90 dollars. Answer: D About 90 dollars. Question:

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Soaring divorce rates around the globe are _ the environment ,American researchers suggested in a study released Monday . Michigan State University researcher Jianguo "Jack "Liu and his assistant Eunice Yu said the increasing number of divorces leads to more households with fewer people and greater consumption of water and energy .They said housing units require space ,construction materials and fuel to heat and cool ,regardless of the number of inhabitants . For example ,in the United States in 2005, divorced households consumed an extra 73 billion kilowatt hours of electricity and 627 billion gallons of water ,An additional 38 million extra rooms required heating and lighting that same year due to divorced households . "A married household actually uses resources more efficiently than a divorced household ", Liu said ,He said that in cohabitating households ,people will watch the same television ,share the air conditioning and heat and use the same refrigerator ,all things that use energy at a regularly stable rate regardless of the number of uses . Liu said he was not condemning divorce ," Some people really need to get divorces "He said cohabitation ---- whether by a family ,friends or even in a commune ------ was simply a more environmentally friendly option ,Additionally ,the researchers noted that trends other than divorce are also changing family living structures ,such as the end of multiple generations of a family sharing a home and people remaining single longer . "People's first reaction to this research is surprise ,and then it seems simple ":Liu said in a release " But a lot of things become simple after research is done .Our challenges were to connect the dots and quantify their relationships People have been talking about how to protect the environment and combat climate change ,but divorce is an overlooked factor that needs to be considered . " He said the increasing energy demands caused by divorce should be considered by governments when they are creating environmental policies . Options: A Critical B Indifferent C Objective D Unclear Answer: C Objective Question:

A: According to the passage ,what's the attitude of Mr. Liu towards divorce ?

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Many people rely on a cup of coffee or two to wake them up in the morning or pick them up during the working day, but now a chemist has come up with a speedy alternative to crafting a cup of coffee. U.S. biochemist Ben Yu has created 'Sprayable Energy,' which claims to be the world's first caffeine - based topical energy spray. He said tired workers can spray a 'shot' of caffeine onto their skin without experiencing a strong buzz, loading up on unnecessary calories or being stuck with a nasty aftertaste like they might get from drinking energy drinks or coffee. The patent-pending caffeine spray is an odourless liquid that is absorbed through the skin and distributed through the body over a number of hours to deliver a caffeine hit that apparently lasts longer than guzzling a cup of coffee. Each small aluminum bottle of Sprayable Energy contains around 160 sprays - the equivalent amount of caffeine to 40 cups of coffee and the creators say it is a much cheaper way of getting a caffeine fix than popping to a cafe. The only active ingredient in the spray is caffeine, which can naturally enter the human body through the skin by passing through cell membranes as it is very similar to nicotine in structure. Each spritz of Sprayable Energy contains around a quarter of the amount of caffeine found in a cup of coffee, but apparently has the same effect as a full cup. The website said: 'The reason for this is our product not being ingested, isn't almost entirely metabolised by the liver before entering your system and becoming available to your body.''Thus, a smaller amount of caffeine can have just the same effect as a very large amount of caffeine ingested through an energy drink or cup of coffee. Sprayable Energy's website recommends that users apply the spray in places where they normally spritz perfume, such as the neck or wrists, but warns users not to exceed 20 sprays a day. It claims that after spraying the product on the skin, users will feel 'awake and focused without being over-stimulated', which is common... Options: A Sprayable Energy can not be permitted to be used by people now. B Sprayable Energy has not already gone into mass production C Each spritz of Sprayable Energy has the same effect as a full cup of coffee D Sprayable Energy is well received by flagging workers. Answer: B Sprayable Energy has not already gone into mass production Question:
