It is bordered by Afghanistan to the south, Uzbekistan to the west, Kyrgyzstan to the north, and China to the east. Pakistan lies to the south, separated by the narrow Wakhan Corridor. Traditional homelands of Tajik people included present-day Tajikistan, Afghanistan and Uzbekistan.

Input: Flowering plant
The apparently sudden appearance of nearly modern flowers in the fossil record initially posed such a problem for the theory of evolution that it was called an "abominable mystery" by Charles Darwin. However, the fossil record has considerably grown since the time of Darwin, and recently discovered angiosperm fossils such as Archaefructus, along with further discoveries of fossil gymnosperms, suggest how angiosperm characteristics may have been acquired in a series of steps. Several groups of extinct gymnosperms, in particular seed ferns, have been proposed as the ancestors of flowering plants, but there is no continuous fossil evidence showing exactly how flowers evolved. Some older fossils, such as the upper Triassic Sanmiguelia, have been suggested. Based on current evidence, some propose that the ancestors of the angiosperms diverged from an unknown group of gymnosperms in the Triassic period (245–202 million years ago). Fossil angiosperm-like pollen from the Middle Triassic (247.2–242.0 Ma) suggests an older date for their origin. A close relationship between angiosperms and gnetophytes, proposed on the basis of morphological evidence, has more recently been disputed on the basis of molecular evidence that suggest gnetophytes are instead more closely related to other gymnosperms.[citation needed]

What type of fossil is the recently discovered Archaefructus?
Output: angiosperm


Input: Article: One of the key concerns of older adults is the experience of memory loss, especially as it is one of the hallmark symptoms of Alzheimer's disease. However, memory loss is qualitatively different in normal aging from the kind of memory loss associated with a diagnosis of Alzheimer's (Budson & Price, 2005). Research has revealed that individuals’ performance on memory tasks that rely on frontal regions declines with age. Older adults tend to exhibit deficits on tasks that involve knowing the temporal order in which they learned information; source memory tasks that require them to remember the specific circumstances or context in which they learned information; and prospective memory tasks that involve remembering to perform an act at a future time. Older adults can manage their problems with prospective memory by using appointment books, for example.

Now answer this question: What do most elderly people worry about?

Output: memory loss,


Article: In September 1828 Chopin, while still a student, visited Berlin with a family friend, zoologist Feliks Jarocki, enjoying operas directed by Gaspare Spontini and attending concerts by Carl Friedrich Zelter, Felix Mendelssohn and other celebrities. On an 1829 return trip to Berlin, he was a guest of Prince Antoni Radziwiłł, governor of the Grand Duchy of Posen—himself an accomplished composer and aspiring cellist. For the prince and his pianist daughter Wanda, he composed his Introduction and Polonaise brillante in C major for cello and piano, Op. 3.

Question: Which opera director did Frédéric see works of during his stay in Berlin?
Ans: Gaspare Spontini


Here is a question about this article: Catalan has few suppletive couplets, like Italian and Spanish, and unlike French. Thus, Catalan has noi/noia ("boy"/"girl") and gall/gallina ("cock"/"hen"), whereas French has garçon/fille and coq/poule.
What is the answer to this question: What kind of words does Catalan have few of?
****
So... suppletive couplets


Article: ARC was acquired in 1938 by the Columbia Broadcasting System (CBS, which, in turn, had been formed by the Columbia Phonograph Company, but then sold off). ARC was renamed Columbia Recording Corporation. The Columbia Phonograph Company had international subsidiaries and affiliates such as the Columbia Graphophone Company in the United Kingdom, but they were sold off prior to CBS acquiring American Columbia. RCA Victor Records executive Ted Wallerstein convinced CBS head William S. Paley to buy ARC and Paley made Wallerstein head of the newly acquired record company. The renamed company made Columbia its flagship label with Okeh its subsidiary label while deemphasizing ARC's other labels. This allowed ARC's leased labels Brunswick Records and Vocalion Records to revert to former owner Warner Bros. which sold the labels to Decca Records. Columbia kept the Brunswick catalogue recorded from December 1931 onward which was reissued on the Columbia label as well as the Vocalion label material from the same time period which was reissued on the Okeh label. Wallerstein, who was promoted at the end of 1947 from president to chairman of the record company, restored Columbia's status as a leading record company and spearheaded the successful introduction of the long playing (LP) record before he retired as Columbia's chairman in 1951. James Conkling then became head of Columbia Records. Also in 1951, Columbia severed its ties with the EMI-owned record label of the same name and began a UK distribution deal with Philips Records, whereas Okeh Records continued to be distributed by EMI on the Columbia label.

Question: Who convinced Paley to buy ARC?
Ans:
RCA Victor Records executive Ted Wallerstein
