Q: Article: EUROPE is home to a variety of cultural treasures. Lonely Planet has offered pairs of cities for culture-hungry but time-poor travelers. London and Paris It takes you about two hours to travel from London to Paris by Eurostar, a high-speed railway service. The two capital cities have been competing in fashion, art and nightlife for decades--but each secretly looks up to the other. No one can doubt the grand and impressive beauty of Paris' Louvre Museum, but if you want to save money, you cannot skip the British Museum free to visit. Compared with London, Paris has more outdoor attractions, such as the beautiful green walkway La Promenade Plantee. In Paris, you'll see diners linger over red wine. While in London, you can try some afternoon tea, eat fish and chips or salted cake. Vienna and Bratislava Austrian capital Vienna and Slovakia city Bratislava are an hour apart by train. But since they are linked by the Danube River, the best way to travel is by ship. A tour of the two cities is the perfect way to experience everything from 17thcentury's Habsburg dynasty splendor to sci-fi restaurants. Vienna is famous for Mozart and imperial palaces. You can appreciate the perfect blending of architecture and nature in the grand Scholoss Schonbrunn Palace, and reward yourself with a cup of Vienna coffee, which has made its way to the world's cultural heritage list. Bratislava is best known for its fine dining--the remarkable UFO restaurant. You can enjoy a meat-laden dinner here in an amazing setting.

Q: Article: I used to think of myself as a fairly open person, but my bookshelves told a different story. Apart from a few Indian novels and the Australian and South African book, my literature collection consisted of British and American titles. Worse still, I hardly ever read anything in translation. My reading was limited to stories by English-speaking authors. So, at the start of 2012, I set myself the challenge of trying to read a book from every country in a year to find out what I was missing. As I was unlikely to find publications from nearly 200 nations on the shelves of my local bookshop, I decided to ask the planet's readers for help. I created a blog called A Year of Reading the World and put out an appeal for suggestions of titles that I could read in English. The response was amazing. Before I knew it, people all over the planet were getting in touch with ideas and offers of help. Some posted me books from their home countries. Others did hours of research on my behalf. In addition, several writers sent me unpublished translations of their novels, giving me a rare opportunity to read works otherwise unavailable to the 62% of the British who only speak English. Even so, selecting books was no easy task. With translations making up only around 4.5 percent of literary works published in the UK and Ireland, getting English versions of stories was difficult. But the effort was worth it. I found I was visiting the mental space of the storytellers. These stories not only opened my mind to the real life in other places, but opened my heart to the way people there might feel. And that in turn changed my thinking. Through reading the stories shared with me by bookish strangers around the globe, I realised I was not alone, but part of a network that spread all over the planet.
Answer: Lists of English version books.

A: Which of the following might be found on the blog A Year of Reading the World?
