Problem: Pharmaceutical industry:

In the U.S., a push for revisions of the FD&C Act emerged from Congressional hearings led by Senator Estes Kefauver of Tennessee in 1959. The hearings covered a wide range of policy issues, including advertising abuses, questionable efficacy of drugs, and the need for greater regulation of the industry. While momentum for new legislation temporarily flagged under extended debate, a new tragedy emerged that underscored the need for more comprehensive regulation and provided the driving force for the passage of new laws.

When did questionable efficacy occur?

Problem: The 100th meridian roughly corresponds with the line that divides the Great Plains into an area that receive 20 inches (510 millimetres) or more of rainfall per year and an area that receives less than 20 in (510 mm). In this context, the High Plains, as well as Southern Alberta, south-western Saskatchewan and Eastern Montana are mainly semi hot steppe land and are generally characterised by rangeland or marginal farmland. The region (especially the High Plains) is periodically subjected to extended periods of drought; high winds in the region may then generate devastating dust storms. The eastern Great Plains near the eastern boundary falls in the humid subtropical climate zone in the southern areas, and the northern and central areas fall in the humid continental climate.
what type of climate does the eastern great plains fall into?
---
Answer: humid subtropical climate

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Dell has been attempting to offset its declining PC business, which still accounted for half of its revenue and generates steady cash flow, by expanding into the enterprise market with servers, networking, software, and services. It avoided many of the acquisition writedowns and management turnover that plagued its chief rival Hewlett Packard. Dell also managed some success in taking advantage of its high-touch direct sales heritage to establish close relationships and design solutions for clients. Despite spending $13 billion on acquisitions to diversify its portfolio beyond hardware, the company was unable to convince the market that it could thrive or made the transformation in the post-PC world, as it suffered continued declines in revenue and share price. Dell's market share in the corporate segment was previously a "moat" against rivals but this has no longer been the case as sales and profits have fallen precipitously.
What happened to Dell's expenses and share price in the post-PC market?
A: unanswerable

Context and question: John von Neumann (/vn nmn/; Hungarian: Neumann Janos Lajos, pronounced [njmn jano ljo]; December 28, 1903 February 8, 1957) was a Hungarian-American pure and applied mathematician, physicist, inventor, computer scientist, and polymath. He made major contributions to a number of fields, including mathematics (foundations of mathematics, functional analysis, ergodic theory, geometry, topology, and numerical analysis), physics (quantum mechanics, hydrodynamics, fluid dynamics and quantum statistical mechanics), economics (game theory), computing (Von Neumann architecture, linear programming, self-replicating machines, stochastic computing), and statistics.
What were Von Neuman's contributions to the field of computing?
Answer: Von Neumann architecture, linear programming, self-replicating machines, stochastic computing

Question: The Appalachian Mountains (i/plen/ or /pltn/,[note 1] French: les Appalaches), often called the Appalachians, are a system of mountains in eastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period and once reached elevations similar to those of the Alps and the Rocky Mountains before they were eroded. The Appalachian chain is a barrier to east-west travel as it forms a series of alternating ridgelines and valleys oriented in opposition to any road running east-west.
Is there an answer to this question: In what era did the mountains form?

Answer: Ordovician Period

The European, American, and Japanese comics traditions have followed different paths. Europeans have seen their tradition as beginning with the Swiss Rodolphe Topffer from as early as 1827 and Americans have seen the origin of theirs in Richard F. Outcault's 1890s newspaper strip The Yellow Kid, though many Americans have come to recognize Topffer's precedence. Japan had a long prehistory of satirical cartoons and comics leading up to the World War II era. The ukiyo-e artist Hokusai popularized the Japanese term for comics and cartooning, manga, in the early 19th century. In the post-war era modern Japanese comics began to flourish when Osamu Tezuka produced a prolific body of work. Towards the close of the 20th century, these three traditions converged in a trend towards book-length comics: the comics album in Europe, the tankobon[a] in Japan, and the graphic novel in the English-speaking countries.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did Outcault's The Yellow Kid appear in newspapers?
Ah, so..
1890s
