Example Input: Article: When it comes to movies, we usually think of big actors, big budgets, big screens, and, if lucky, big profits. Unfortunately, that puts up some big barriers for aspiring young filmmakers and their dreams. However, thanks to easy access to technology, that's all changing. All one really needs nowadays is a camera, a computer, an Internet connection, and, of course, a good idea. With that, you can enter the microfilm world. Shooting a movie using friends and family as the cast has become a common class project for high school students. After a little editing on a laptop, some even decide their creation is worth sharing online. Microfilms are shot within a short period of time and last only a few minutes or even shorter. Most are completed on an extremely small budget and offer a cheap way for grassroots directors to realize their dreams. With a range of film festivals, they have taken off due to being perfectly suited to new media platforms such as mobile phones and notebook computers. They are also easily shared across social networks and microblogs. But microfilms are far different from the shorts commonly found on YouTube. A microfilm must have a solid and thoughtful plot. Most importantly, the movies are easily distributed and there can be no concern about long-term box office profits. Most people who upload a microfilm simply see it as an easy way to share their fun with a few friends and family. Others may be curious about what sort of reaction their production may receive from the general public.
Question: According to the passage, what helps promising microfilmmakers realize their dreams?
Options: (A) The profits from microfilms. (B) Aids from friends and family. (C) Supports from the public. (D) Small costs for microfilms.
Example Output: D

Example Input: Article: Signs in Chinese will be set up in public areas such as airports, to benefit Chinese travelers, the Italian Government announced in late February. _ . Despite the different languages, travel across Europe has never been so simple. Just five years ago, if you wanted to visit Germany in the north and Spain in the south in one trip, you had to wait for weeks to apply for different visas from the two countries. You also needed a calculator because both countries had different money. Today, with a Schengen Visa issued by any member country, you can travel across 15 European countries without stopping. Since 2002, within most of the EU, there is now just one type of money called the Euro. The Euro was designed to be the only money in the EU, and already makes it easier to shop around. If you drive, your driving license and car insurance policy are valid in the other European countries. And you can use your mobile phone everywhere. All the countries in the continent are melting into a united Europe under the EU. For Europeans and visitors, the result is that it is more convenient to travel back and forth between the different countries.
Question: Compared to five years ago, traveling in Europe has become easier because _ .
Options: (A) you needn't drive a car (B) you can use a calculator to exchange money (C) applying for different visas is much simpler (D) one visa is good enough for traveling in a number of countries
Example Output: D

Example Input: Article: The great Snipe is a little shore bird-not one that would be considered a great athlete. However, a recent study has shown that these slightly fat birds not only fly nonstop for long periods of time during their annual migration, but do so at record speeds. The brown migratory birds that are about the size of a pigeon spend their summers in Eastern Europe and winters in Central Africa, a distance of about 2,800 to 4,000 miles. In May 2009, a team of researchers led by Dr. Raymond Klaasen from Sweden's Lund University fitted ten Great Snipes with tiny geo-locating devices that allow scientists to figure out when and where the birds travel, and let them loose. The following year they found three of the birds and took back the devices. What they discovered was quite _ . All three birds had flown nonstop to Central Africa in August of 2009-one had flown 4,225 miles in just 3.5 days. The second one had covered a distance of 3,833 miles in three days, while the third had managed to fly 2,870 miles in a mere 48 hours or two days. Even more surprising was that these birds had traveled at speeds that averaged about 50 miles per hour-making it the fastest known migration ever. While many birds migrate longer distances, they do so over a period of a few months, resting and feeding in between. However, despite the fact the Great Snipe has plenty of opportunities, it does not stop. And they do the entire flight with their own power, with no assistance from the wind. The tiny bird is able to make this unbelievable direct flight because of all the fat it gradually gathers in its body, which it then uses as fuel. Native no North Eastern Europe, Great Snipes live in marshlands and wet meadows . But they are also on the list of endangered animals because of loss of habitat.
Question: What is the text mainly about?
Options: (A) A new device used to follow birds (B) A recent research on endangered birds (C) A unique migration route of birds (D) An unusual species of migratory bird
