Problem: For decades, the U.S. federal government strenuously tried to force Puerto Ricans to adopt English, to the extent of making them use English as the primary language of instruction in their high schools. It was completely unsuccessful, and retreated from that policy in 1948. Puerto Rico was able to maintain its Spanish language, culture, and identity because the relatively small, densely populated island was already home to nearly a million people at the time of the U.S. takeover, all of those spoke Spanish, and the territory was never hit with a massive influx of millions of English speakers like the vast territory acquired from Mexico 50 years earlier.
How did Puerto Rico stay an English speaking territory?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The dynasty lost control of peripheral territories bit by bit. In return for promises of support against the British and the French, the Russian Empire took large chunks of territory in the Northeast in 1860. The period of cooperation between the reformers and the European powers ended with the Tientsin Massacre of 1870, which was incited by the murder of French nuns set off by the belligerence of local French diplomats. Starting with the Cochinchina Campaign in 1858, France expanded control of Indochina. By 1883, France was in full control of the region and had reached the Chinese border. The Sino-French War began with a surprise attack by the French on the Chinese southern fleet at Fuzhou. After that the Chinese declared war on the French. A French invasion of Taiwan was halted and the French were defeated on land in Tonkin at the Battle of Bang Bo. However Japan threatened to enter the war against China due to the Gapsin Coup and China chose to end the war with negotiations. The war ended in 1885 with the Treaty of Tientsin (1885) and the Chinese recognition of the French protectorate in Vietnam.
When was the Tientsin Massacre?
A: 1870

Question: Daniel L. Magruder, Jr defines USAF culture as a combination of the rigorous application of advanced technology, individualism and progressive airpower theory. Major General Charles J. Dunlap, Jr. adds that the U.S. Air Force's culture also includes an egalitarianism bred from officers perceiving themselves as their service's principal "warriors" working with small groups of enlisted airmen either as the service crew or the onboard crew of their aircraft. Air Force officers have never felt they needed the formal social "distance" from their enlisted force that is common in the other U.S. armed services. Although the paradigm is changing, for most of its history, the Air Force, completely unlike its sister services, has been an organization in which mostly its officers fought, not its enlisted force, the latter being primarily a rear echelon support force. When the enlisted force did go into harm's way, such as members of multi-crewed aircraft, the close comradeship of shared risk in tight quarters created traditions that shaped a somewhat different kind of officer/enlisted relationship than exists elsewhere in the military.
Is there an answer to this question: How have the enlisted forces of the US Air Force been seen?

Answer: primarily a rear echelon support force
