Question: The status of "language" is not solely determined by linguistic criteria, but it is also the result of a historical and political development. Romansh came to be a written language, and therefore it is recognized as a language, even though it is very close to the Lombardic alpine dialects. An opposite example is the case of Chinese, whose variations such as Mandarin and Cantonese are often called dialects and not languages, despite their mutual unintelligibility.
Is there an answer to this question: Which variations of the Chinese language have mutual intelligibility? 

Answer: unanswerable


Question: Eisenhower's goal to create improved highways was influenced by difficulties encountered during his involvement in the U.S. Army's 1919 Transcontinental Motor Convoy. He was assigned as an observer for the mission, which involved sending a convoy of U.S. Army vehicles coast to coast. His subsequent experience with encountering German autobahn limited-access road systems during the concluding stages of World War II convinced him of the benefits of an Interstate Highway System. Noticing the improved ability to move logistics throughout the country, he thought an Interstate Highway System in the U.S. would not only be beneficial for military operations, but provide a measure of continued economic growth. The legislation initially stalled in the Congress over the issuance of bonds to finance the project, but the legislative effort was renewed and the law was signed by Eisenhower in June 1956.
Is there an answer to this question: Why did Congress hold up the highway bill?

Answer:
issuance of bonds to finance the project
