In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.

Example Input: Article: Recent research has claimed that an excess of positive ions in the air can have an ill effect on people's physical or psychological health. What are positive ions? Well, the air is full of ions, electrically charged particles, and generally there is a rough balance between the positive and the negative charged. But sometimes this balance becomes disturbed and a larger proportion of positive ions are found. This happens naturally before thunderstorm, earthquakes when winds are blowing in certain countries. Or it can be caused by a build-up of static electricity indoors from carpets or clothing, or from TV sets, duplicators or computer display screens. When a large number of positive ions are present in the air many people experience unpleasant effects such as headaches, fatigue , excessive anger, and some particularly sensitive people feel sick or even suffer mental disturbance. Animals are also affected, particularly before earthquakes, snakes have been observed to come out, rats to flee from their burrows, dogs howl and cats jump about unaccountably. This has led the US Geographical Survey to fund a network of volunteers to watch animals in an effort to foresee such disasters before they hit vulnerable areas such as California. Conversely, when large numbers of negative ions are present, then people have a feeling of well-being. Natural conditions that produce these large amounts are near the sea, close to waterfalls or fountains, or in any place where water is sprayed, or forms a spray. This probably accounts for the beneficial effect of a holiday by the sea, or in the mountains with streams or waterfalls. To increase the supply of negative ions indoors, some scientists recommend the use of ionisers. They claim that ionisers not only clean and refresh the air but also improve the health of people sensitive to excess positive ions. Of course, there are the detractors, other scientists, who dismiss such claims and are skeptical about negative/positive ion research. Therefore people can only make up their own minds by observing the effects on themselves, or on others, of a negative rich or poor environment. After all it is debatable whether depending on seismic readings to anticipate earthquakes is more effective than watching the cat.
Answer: It's a charged particle.
Example Output: What is an ion according to the passage?

Example Input: Article: Nearly 60 million visitors flooded to the 384 national parks across America every year. And you won't have to wander far from home to enjoy one of these national treasures, with Michigan's Isle Royale National Park nearby. Located 56 miles from Copper Harbor on Michigan's Upper Peninsula, the park remains _ that can only be reached by tour boat. With the exception of the Rock Harbor Lodge, which offers both rooms with private baths and accommodations in the form of small cottages, the 572,000 acres that make up the 45-mile-long park are rough, threaded with hiking paths that lead to tents-only campsites. You are likely to see a deer crossing mist-covered ponds in search of breakfast, gaze bald eagles flying overhead, or hear a beaver clapping its tail on the water. If you are especially lucky, you might even glimpse a grey wolf, nearly dying out from hunting on the mainland. Plenty of hiking paths open the area to exploration. The 4-mile Stroll Path winds through various trees and offers a tour of the island's history, including prehistoric Indian mines. The Jungle Path leads to Scoville Point----a perfect picnic spot surrounded on three sides by the shining waters of Lake Superior. You can also rent a boat at the park's service center and row down the shore to the Rock Harbor Lighthouse. Here park's service employees use nets to show how lake fishes used to be caught by the original local people. Their catch ends up on the dinner menu at the Rock Harbor Lodge. The park is open from mid-April through October; Rock Harbor Lodge is open from Memorial Day weekend until just after Labor Day.
Answer: Food provided by Rock Harbor Lodge is shipped from outside.
Example Output: What can we infer from the passage?

Example Input: Article: The day my husband fell to his death,it started to snow,just like any November day.His body,when I found it,was lightly covered with snow.It snowed almost every day for the next four months,while I sat on the couch and watched it pile up.One morning,I _ downstairs and was surprised to see a snow remover clearing my driveway and the bent back of a woman shoveling my walk.I dropped to my knees,crawled through the living room.And back up stairs so those good people would not see me.I was embarrassed.My first thought was,how would I ever repay them? I didn't have the strength to brush my hair let alone shovel someone's walk. Before John's death,I took pride in the fact that I rarely asked for help or favors,I defined myself by my competence and independence.So who was I if I was no longer capable and busy? How could I respect myself if all I did was sit on the couch every day and watch the snowfall? Learning how to receive the love and support that came my way wasn't easy.Friends cooked forme and l cried because I couldn't even help them set the table."I'm not usually this lazy,"I wept.Finally,my friend Kathy sat down with me and said,"Mary,cooking for you is not a burden. I love you and I want to do it.It makes me feel good to be able to do something for you." Over and over,I heard similar emotions from the people who supported me during those dark days.One very wise man told me,"You are not doing nothing.Being fully open to your sorrow may be the hardest work you will everdo." I am not the person I once was,but in many ways I have changed for the better.My heart is now filled with thanks for people around me.I have been surprised to learn that there is incredible freedom that comes from facing one's worst fear and walking away whole.I believe there is strength,for sure,in accepting a dark period of our life.
