After losing two grandparents within the past year, I have taken some time to reflect on what is most important.I want to let you know what a positive influence you have been on me.I am the person I am because of you. I remember being on your farm a lot when I was younger.I remember the projects you planned for us.We painted rocks to represent our family members.We made doll clothes out of colorful socks.We made many "playhouses" in the woods. We learned that if you left a bucket of soybeans in the rain, you would soon have a bucket of growing beans.We learned that if we helped pick the strawberries in the morning, we'd have them on our ice cream in the afternoon.We learned that some plants have funny names, like the elephant ear plant.We learned that you could make do with what you had.We learned that making things out of paper and cardboard was more fun than what came inside the packaging.We learned it was OK to get dirty, but Grandma would wash us up before Mom came. You once made models of everyone's houses, which made me want to be an architect.Another time, you made quilts for all of the grandkids.I still use mine every night.The edge has worn out. But you taught me how to fix it. I love and respect you.You are always patient, with a quiet determination. Grandma, thank you for everything you have taught me.I hope that I am able to pass on all these memories and skills to my children and grandchildren. Love always, Kelly Options: A send her grandma best wishes for Christmas B show love and respect for her grandma C recall her happy life on the farm D ask her grandma for help Answer: B show love and respect for her grandma Question:???

Write a multi-choice question for the following article, with the given choices and answer: Article: Feeling blue about world ? "Cheer up." Says science writer Matt Ridley."The world has never been a better place to live in, and it will keep on getting better both for humans and got nature." Ridley calls himself a tat ional optimist--tactical .because he's carefully weighed the evidence optimistic .because that offence shows human progress to be both unavoidable and good .And this is what he's set out to prone from unique point of view in his most recent book. The Rant anal Opting .He views mankind as grand enterprise that .on the whole .has done little but progress for 100.000 years. He backed his finding with hard gathered though years of research. Here's how he explains his views. Shopping fuels invention It is reported that there are more than ten billion different producers for sale in London alone. Even allowing for the many people who still live in poverty .our own generation has access to more nutritious food .more convenient transport .bigger houses, better ears .and of course, more pounds and dollars than any who lived before us .This will continue as long as we there things to make other things, This more we specialize and exchange, the better off we'll be. 2) Brilliant advances One reason we are richer, healthier, taller, cleverer, longer-lived and freer than ener before is that the four most basie human needs -food, clothing, fuel and shelter- have grown a lot cheaper. Take one example. In 1800 a candle providing one hour's light cost six hours' work. In the 1880s the same light from an oil lamp took 15 minutes' work to pay for. In 1950 it was eight seconds. Today it's half second. 3) Let's not kill ourselves for climate change Mitigating climate change could prove just as damaging to human welface as climate change itself. A child that dies from indoor smoke in a village, where the use of fassil-fuel electrieity is forhidden by well meaming members of green polucal movements trying to save the world, is just as great a tragedy as a child that mes in a flood caused by climate change. If... Options: A oil lamps give off more light than candles B shortening working time brings about a happier life. C advanced technology helps to produce better candles. D increased production rate leads to lower cost of goods. Answer: D increased production rate leads to lower cost of goods. Question:
----
Answer: The candle and lamp example is used to show that .

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: While astronauts in space get to do many exciting things, they miss out on ordinary things that we all take for granted--being able to walk on firm ground, hanging out with family and digging into a slice of hot steaming pizza. Though not much can be done about the first two things, there may soon be a solution to the third one, thanks to this cool 3-D pizza printer! About a year ago, NASA offered $125 ,000 to Anjan Contractor, a 3-D technology expert, to build a device that would allow astronauts to make pizza on demand. The mechanical engineer promised that his invention would produce pies in large quantities that looked, tasted and even smelled like pizza made in common ovens. Late last year, the engineer presented a video of his first prototype that begins by creating a single slice of dough that is cooked and printed at the same time. Then comes the tomato "sauce" -- a mix of tomato powder, oil and water and finally, a protein slice that resembles cheese. While the video doesn't show the baking process, the inventor says that once the pizza is printed, it can be ready to be consumed in 7 seconds. While the pie in the video looks delicious enough to attract any pizza lover, Anjan Contractor is far from ready for astronauts. That's because he still has to find a solution to make the food container in the printer last for 30 years. Though that may sound unrealistic, actually it is not. Anjan Contractor believes that the only way that is possible is that the water is removed from all the ingredients and then they are reduced to the powder form. This, as you can imagine, will not be so easy. But, while the printer may not be ready for space, it certainly looks ready enough for people on earth. Hopefully, NASA and Contractor will consider selling it to those not fortunate enough to go to Mars! Options: A create some new type of 3-D printer B attract more companies to work for NASA C help astronauts in space enjoy fresh pizza one day D produce pizza in large quantities to earn great profits Answer: C help astronauts in space enjoy fresh pizza one day Question:
