Here is a question about this article: Most of Hume's followers have disagreed with his conclusion that belief in an external world is rationally unjustifiable, contending that Hume's own principles implicitly contained the rational justification for such a belief, that is, beyond being content to let the issue rest on human instinct, custom and habit. According to an extreme empiricist theory known as phenomenalism, anticipated by the arguments of both Hume and George Berkeley, a physical object is a kind of construction out of our experiences. Phenomenalism is the view that physical objects, properties, events (whatever is physical) are reducible to mental objects, properties, events. Ultimately, only mental objects, properties, events, exist hence the closely related term subjective idealism. By the phenomenalistic line of thinking, to have a visual experience of a real physical thing is to have an experience of a certain kind of group of experiences. This type of set of experiences possesses a constancy and coherence that is lacking in the set of experiences of which hallucinations, for example, are a part. As John Stuart Mill put it in the mid-19th century, matter is the "permanent possibility of sensation". Mill's empiricism went a significant step beyond Hume in still another respect: in maintaining that induction is necessary for all meaningful knowledge including mathematics. As summarized by D.W. Hamlin:

So... belief in an external world

Here is a question about this article: The central government estimates that over 7,000 inadequately engineered schoolrooms collapsed in the earthquake. Chinese citizens have since invented a catch phrase: "tofu-dregs schoolhouses" (Chinese: ), to mock both the quality and the quantity of these inferior constructions that killed so many school children. Due to the one-child policy, many families lost their only child when schools in the region collapsed during the earthquake. Consequently, Sichuan provincial and local officials have lifted the restriction for families whose only child was either killed or severely injured in the disaster. So-called "illegal children" under 18 years of age may be registered as legal replacements for their dead siblings; if the dead child was illegal, no further outstanding fines would apply. Reimbursement would not, however, be offered for fines that were already levied.
What is the answer to this question: How many schoolrooms collapsed in the quake?

So... 7,000

Here is a question about this article: The second-largest commercial airport is William P. Hobby Airport (named Houston International Airport until 1967) which operates primarily short- to medium-haul domestic flights. However, in 2015 Southwest Airlines launched service from a new international terminal at Hobby airport to several destinations in Mexico, Central America, and the Caribbean. These were the first international flights flown from Hobby since 1969. Houston's aviation history is showcased in the 1940 Air Terminal Museum located in the old terminal building on the west side of the airport. Hobby Airport has been recognized with two awards for being one of the top five performing airports in the world and for customer service by Airports Council International.
What is the answer to this question: Which airline now offers international flights from Hobby Airport?

So...
Southwest Airlines
