input question: Question: "What shape is DNA?" Context: "Two chains of DNA twist around each other to form a DNA double helix with the phosphate-sugar backbone spiralling around the outside, and the bases pointing inwards with adenine base pairing to thymine and guanine to cytosine. The specificity of base pairing occurs because adenine and thymine align form two hydrogen bonds, whereas cytosine and guanine form three hydrogen bonds. The two strands in a double helix must therefore be complementary, with their sequence of bases matching such that the adenines of one strand are paired with the thymines of the other strand, and so on.:4.1" Answer:???
output answer: double helix

input question: Question: "What category does the early form of semi-cursive script belong to?" Context: "By the late Eastern Han period, an early form of semi-cursive script appeared, developing out of a cursively written form of neo-clerical script[c] and simple cursive. This semi-cursive script was traditionally attributed to Liu Desheng c. 147188 AD,[d] although such attributions refer to early masters of a script rather than to their actual inventors, since the scripts generally evolved into being over time. Qiu gives examples of early semi-cursive script, showing that it had popular origins rather than being purely Liu's invention." Answer:???
output answer: cursive

input question: Question: "Where is the stop?" Context: "Amtrak's Northeast Corridor and Chicago lines originate at South Station, which serves as a major intermodal transportation hub, and stop at Back Bay. Fast Northeast Corridor trains, which serve New York City, Washington, D.C., and points in between, also stop at Route 128 Station in the southwestern suburbs of Boston. Meanwhile, Amtrak's Downeaster service to Maine originates at North Station, despite the current lack of a dedicated passenger rail link between the two railhubs, other than the "T" subway lines." Answer:???
output answer: southwestern suburbs of Boston

input question: Question: "What is the Swainson's thrush Catharus ustulatus' ultimate migratory destination?" Context: "Theoretical analyses show that detours that increase flight distance by up to 20% will often be adaptive on aerodynamic grounds - a bird that loads itself with food to cross a long barrier flies less efficiently. However some species show circuitous migratory routes that reflect historical range expansions and are far from optimal in ecological terms. An example is the migration of continental populations of Swainson's thrush Catharus ustulatus, which fly far east across North America before turning south via Florida to reach northern South America; this route is believed to be the consequence of a range expansion that occurred about 10,000 years ago. Detours may also be caused by differential wind conditions, predation risk, or other factors." Answer:???
output answer:
northern South America
