Student A:γ-Amylase (EC 3.2. 1.3) (alternative names: Glucan 1, 4-α-glucosidase; amyloglucosidase; Exo-1, 4-α-glucosidase; glucoamylase; lysosomal α-glucosidase; 1, 4-α-D-glucan glucohydrolase) will cleave α (1 -- 6) glycosidic linkages, as well as the last α (1 -- 4) glycosidic linkages at the nonreducing end of amylose and amylopectin, yielding glucose. The γ-amylase has most acidic optimum pH of all amylases because it is most active around pH 3.

Answer this question: which type of amylase will cleave both α-1 4 and α-1 6 glycosidic bonds?
Student B:OK... The relevant information is: γ-Amylase (EC 3.2. 1.3) (alternative names: Glucan 1, 4-α-glucosidase; amyloglucosidase; Exo-1, 4-α-glucosidase; glucoamylase; lysosomal α-glucosidase; 1, 4-α-D-glucan glucohydrolase) will cleave α (1 -- 6) glycosidic linkages, as well as the last α (1 -- 4) glycosidic linkages at the nonreducing end of amylose and amylopectin, yielding glucose.
γ - Amylase ( EC 3.2. 1.3 ) ( alternative names : Glucan 1 , 4 - α - glucosidase ; amyloglucosidase ; Exo - 1 , 4 - α - glucosidase ; glucoamylase ; lysosomal α - glucosidase ; 1 , 4 - α - D - glucan glucohydrolase ).

Student A:Context: Springfield's original name was Calhoun, after Senator John C. Calhoun of South Carolina. The land that Springfield now occupies was originally settled by trappers and traders who came to the Sangamon River in 1818. The settlement's first cabin was built in 1820, by John Kelly. It was located at what is now the northwest corner of Second Street and Jefferson Street. In 1821, Calhoun became the county seat of Sangamon County due to fertile soil and trading opportunities. Settlers from Kentucky, Virginia, and as far as North Carolina came to the city. By 1832, Senator Calhoun had fallen out of the favor with the public and the town renamed itself Springfield after Springfield, Massachusetts. At that time, Springfield, Massachusetts was comparable to modern-day Silicon Valley -- known for industrial innovation, concentrated prosperity, and the celebrated Springfield Armory. Most importantly, it was a city that had built itself up from frontier outpost to national power through ingenuity -- an example that the newly named Springfield, Illinois, sought to emulate. Kaskaskia was the first capital of the Illinois Territory from its organization in 1809, continuing through statehood in 1818, and through the first year as a state in 1819. Vandalia was the second state capital of Illinois from 1819 to 1839. Springfield became the third and current capital of Illinois in 1839. The designation was largely due to the efforts of Abraham Lincoln and his associates; nicknamed the "Long Nine" for their combined height of 54 feet (16 m).

Question: when did springfield become the capital of illinois?
Student B:OK... To answer this question, we should know that: Springfield became the third and current capital of Illinois in 1839.

Student A:The fifth-wheel coupling provides the link between a semi-trailer and the towing truck, tractor unit, leading trailer or dolly. Some camper trailers use a fifth-wheel configuration, requiring the coupling to be installed in the bed of a pickup truck as a towing vehicle, and "fifth wheel" is therefore sometimes used as a synonym for such campers in North America. The coupling consists of a kingpin, a 2-or-3 ⁄-inch-diameter (50.8 or 88.9 mm) vertical steel pin protruding from the bottom of the front of the semi-trailer, and a horseshoe-shaped coupling device called a fifth wheel on the rear of the towing vehicle.

Why is it called a 5th wheel trailer?
Student B:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
