Southeastern Pennsylvania was assigned the 215 area code in 1947 when the North American Numbering Plan of the "Bell System" went into effect. The geographic area covered by the code was split nearly in half in 1994 when area code 610 was created, with the city and its northern suburbs retaining 215. Overlay area code 267 was added to the 215 service area in 1997, and 484 was added to the 610 area in 1999. A plan in 2001 to introduce a third overlay code to both service areas (area code 445 to 215, area code 835 to 610) was delayed and later rescinded.
When was the 267 added?
1997

Input: Crimean War
It is often said that Russia was militarily weak, technologically backward, and administratively incompetent. Despite its grand ambitions toward the south, it had not built its railroad network in that direction, and communications were poor. The bureaucracy was riddled with graft, corruption and inefficiency and was unprepared for war. Its navy was weak and technologically backward; its army, although very large, was good only for parades, suffered from colonels who pocketed their men's pay, poor morale, and was out of touch with the latest technology developed by Britain and France. By the war's end, everyone realized the profound weaknesses of the Russian military, and the Russian leadership was determined to reform it.

What did Russian colonels due to the men who served under them?
Output: pocketed their men's pay

Input: Article: The majority of eukaryotic genes are stored on a set of large, linear chromosomes. The chromosomes are packed within the nucleus in complex with storage proteins called histones to form a unit called a nucleosome. DNA packaged and condensed in this way is called chromatin.:4.2 The manner in which DNA is stored on the histones, as well as chemical modifications of the histone itself, regulate whether a particular region of DNA is accessible for gene expression. In addition to genes, eukaryotic chromosomes contain sequences involved in ensuring that the DNA is copied without degradation of end regions and sorted into daughter cells during cell division: replication origins, telomeres and the centromere.:4.2 Replication origins are the sequence regions where DNA replication is initiated to make two copies of the chromosome. Telomeres are long stretches of repetitive sequence that cap the ends of the linear chromosomes and prevent degradation of coding and regulatory regions during DNA replication. The length of the telomeres decreases each time the genome is replicated and has been implicated in the aging process. The centromere is required for binding spindle fibres to separate sister chromatids into daughter cells during cell division.:18.2

Now answer this question: Chromosomes that are packed within the nucleus in complex with histones are called what?

Output: a nucleosome

Article: The World Intellectual Property Organization (WIPO) recognizes that conflicts may exist between the respect for and implementation of current intellectual property systems and other human rights. In 2001 the UN Committee on Economic, Social and Cultural Rights issued a document called "Human rights and intellectual property" that argued that intellectual property tends to be governed by economic goals when it should be viewed primarily as a social product; in order to serve human well-being, intellectual property systems must respect and conform to human rights laws. According to the Committee, when systems fail to do so they risk infringing upon the human right to food and health, and to cultural participation and scientific benefits. In 2004 the General Assembly of WIPO adopted The Geneva Declaration on the Future of the World Intellectual Property Organization which argues that WIPO should "focus more on the needs of developing countries, and to view IP as one of many tools for developmentnot as an end in itself".

Question: When did the WIPO adopt 'The Geneva Declaration on the Future of the World Intellectual Property Organization'?
Ans: 2004

Here is a question about this article: Plant anatomy is the study of the structure of plant cells and tissues, whereas plant morphology is the study of their external form. All plants are multicellular eukaryotes, their DNA stored in nuclei. The characteristic features of plant cells that distinguish them from those of animals and fungi include a primary cell wall composed of the polysaccharides cellulose, hemicellulose and pectin, larger vacuoles than in animal cells and the presence of plastids with unique photosynthetic and biosynthetic functions as in the chloroplasts. Other plastids contain storage products such as starch (amyloplasts) or lipids (elaioplasts). Uniquely, streptophyte cells and those of the green algal order Trentepohliales divide by construction of a phragmoplast as a template for building a cell plate late in cell division.
What is the answer to this question: Where do plants store their DNA?
****
So... in nuclei

Article: Following a custom she maintained throughout her widowhood, Victoria spent the Christmas of 1900 at Osborne House on the Isle of Wight. Rheumatism in her legs had rendered her lame, and her eyesight was clouded by cataracts. Through early January, she felt "weak and unwell", and by mid-January she was "drowsy ... dazed, [and] confused". She died on Tuesday, 22 January 1901, at half past six in the evening, at the age of 81. Her son and successor King Edward VII, and her eldest grandson, Emperor Wilhelm II of Germany, were at her deathbed. Her favourite pet Pomeranian, Turri, was laid upon her deathbed as a last request.

Question: What had caused Victoria to be lame?
Ans:
Rheumatism in her legs
