Problem: History of science:

Historical linguistics emerged as an independent field of study at the end of the 18th century. Sir William Jones proposed that Sanskrit, Persian, Greek, Latin, Gothic, and Celtic languages all shared a common base. After Jones, an effort to catalog all languages of the world was made throughout the 19th century and into the 20th century. Publication of Ferdinand de Saussure's Cours de linguistique generale created the development of descriptive linguistics. Descriptive linguistics, and the related structuralism movement caused linguistics to focus on how language changes over time, instead of just describing the differences between languages. Noam Chomsky further diversified linguistics with the development of generative linguistics in the 1950s. His effort is based upon a mathematical model of language that allows for the description and prediction of valid syntax. Additional specialties such as sociolinguistics, cognitive linguistics, and computational linguistics have emerged from collaboration between linguistics and other disciplines.

What did Noam Chomsky add to the study of linguistics?

A: the development of generative linguistics

Problem: The earliest evidence of cotton use in South Asia has been found at the site of Mehrgarh, Pakistan, where cotton threads have been found preserved in copper beads; these finds have been dated to Neolithic (between 6000 and 5000 BCE). Cotton cultivation in the region is dated to the Indus Valley Civilization, which covered parts of modern eastern Pakistan and northwestern India between 3300 and 1300 BCE The Indus cotton industry was well-developed and some methods used in cotton spinning and fabrication continued to be used until the industrialization of India. Between 2000 and 1000 BC cotton became widespread across much of India. For example, it has been found at the site of Hallus in Karnataka dating from around 1000 BC.
When did cotton cover parts of Inida and Pakistan?

Context and question: The wider New York City metropolitan area, with over 20 million people, about 50% greater than the second-place Los Angeles metropolitan area in the United States, is also ethnically diverse. The New York region continues to be by far the leading metropolitan gateway for legal immigrants admitted into the United States, substantially exceeding the combined totals of Los Angeles and Miami, the next most popular gateway regions. It is home to the largest Jewish as well as Israeli communities outside Israel, with the Jewish population in the region numbering over 1.5 million in 2012 and including many diverse Jewish sects from around the Middle East and Eastern Europe. The metropolitan area is also home to 20% of the nation's Indian Americans and at least 20 Little India enclaves, as well as 15% of all Korean Americans and four Koreatowns; the largest Asian Indian population in the Western Hemisphere; the largest Russian American, Italian American, and African American populations; the largest Dominican American, Puerto Rican American, and South American and second-largest overall Hispanic population in the United States, numbering 4.8 million; and includes at least 6 established Chinatowns within New York City alone, with the urban agglomeration comprising a population of 779,269 overseas Chinese as of 2013 Census estimates, the largest outside of Asia.
As of 2012, how many Jewish people lived in the New York metropolitan area?
Answer: 1.5 million

Question: Notably, a statute does not disappear automatically merely because it has been found unconstitutional; it must be deleted by a subsequent statute. Many federal and state statutes have remained on the books for decades after they were ruled to be unconstitutional. However, under the principle of stare decisis, no sensible lower court will enforce an unconstitutional statute, and any court that does so will be reversed by the Supreme Court. Conversely, any court that refuses to enforce a constitutional statute (where such constitutionality has been expressly established in prior cases) will risk reversal by the Supreme Court.
Is there an answer to this question: What decisis states that no lower court will enforce an unconstitutional statute?

Answer: the principle of stare decisis
