Article: In the 1930s, the experimental station W3XE, owned by Philco, became the first television station in Philadelphia; it became NBC's first affiliate in 1939, and later became KYW-TV (CBS). WCAU-TV, WPVI-TV, WHYY-TV, WPHL-TV, and WTXF-TV had all been founded by the 1970s. In 1952, WFIL (now WPVI) premiered the television show Bandstand, which later became the nationally broadcast American Bandstand hosted by Dick Clark.

The region is served also by public broadcasting stations WYBE-TV (Philadelphia), WHYY-TV (Wilmington, Delaware and Philadelphia), WLVT-TV (Lehigh Valley), and NJTV (New Jersey). In September 2007, Philadelphia approved a Public-access television cable TV channel.

Here is a question about this article: The Great Plains lie west of the Mississippi River and east of the Rocky Mountains. A large portion of the country's agricultural products are grown in the Great Plains. Before their general conversion to farmland, the Great Plains were noted for their extensive grasslands, from tallgrass prairie in the eastern plains to shortgrass steppe in the western High Plains. Elevation rises gradually from less than a few hundred feet near the Mississippi River to more than a mile high in the High Plains. The generally low relief of the plains is broken in several places, most notably in the Ozark and Ouachita Mountains, which form the U.S. Interior Highlands, the only major mountainous region between the Rocky Mountains and the Appalachian Mountains.
What is the answer to this question: What area is located in between the Mississippi River and the Rocky Mountains?
****
So... The Great Plains

Problem: Please answer a question about the following article about Orthodox Judaism:
For guidance in practical application of Jewish law, the majority of Orthodox Jews appeal to the Shulchan Aruch ("Code of Jewish Law" composed in the 16th century by Rabbi Joseph Caro) together with its surrounding commentaries. Thus, at a general level, there is a large degree of uniformity amongst all Orthodox Jews. Concerning the details, however, there is often variance: decisions may be based on various of the standardized codes of Jewish Law that have been developed over the centuries, as well as on the various responsa. These codes and responsa may differ from each other as regards detail (and reflecting the above philosophical differences, as regards the weight assigned to these). By and large, however, the differences result from the historic dispersal of the Jews and the consequent development of differences among regions in their practices (see minhag).
there is a large degree of what amongst all orthodox jews?
A: uniformity
