Input: Read this: In nature, uranium(VI) forms highly soluble carbonate complexes at alkaline pH. This leads to an increase in mobility and availability of uranium to groundwater and soil from nuclear wastes which leads to health hazards. However, it is difficult to precipitate uranium as phosphate in the presence of excess carbonate at alkaline pH. A Sphingomonas sp. strain BSAR-1 has been found to express a high activity alkaline phosphatase (PhoK) that has been applied for bioprecipitation of uranium as uranyl phosphate species from alkaline solutions. The precipitation ability was enhanced by overexpressing PhoK protein in E. coli.
Question: What type of complexes does uranium(VI) form in nature?

Output: carbonate

QUES: Geologically, Plymouth has a mixture of limestone, Devonian slate, granite and Middle Devonian limestone. Plymouth Sound, Shores and Cliffs is a Site of Special Scientific Interest, because of its geology. The bulk of the city is built upon Upper Devonian slates and shales and the headlands at the entrance to Plymouth Sound are formed of Lower Devonian slates, which can withstand the power of the sea.

What special designation does Plymouth Sound, Shores and Cliffs possess?
What is the answer?
ANS: Site of Special Scientific Interest

QUES: Currents induced into this winding provide the rotor magnetic field. The shape of the rotor bars determines the speed-torque characteristics. At low speeds, the current induced in the squirrel cage is nearly at line frequency and tends to be in the outer parts of the rotor cage. As the motor accelerates, the slip frequency becomes lower, and more current is in the interior of the winding. By shaping the bars to change the resistance of the winding portions in the interior and outer parts of the cage, effectively a variable resistance is inserted in the rotor circuit. However, the majority of such motors have uniform bars.
What doesn't determine the properties of speed and torque?

ANS: unanswerable

Vinyl records can be warped by heat, improper storage, exposure to sunlight, or manufacturing defects such as excessively tight plastic shrinkwrap on the album cover. A small degree of warp was common, and allowing for it was part of the art of turntable and tonearm design. "wow" (once-per-revolution pitch variation) could result from warp, or from a spindle hole that was not precisely centered. Standard practice for LPs was to place the LP in a paper or plastic inner cover. This, if placed within the outer cardboard cover so that the opening was entirely within the outer cover, was said to reduce ingress of dust onto the record surface. Singles, with rare exceptions, had simple paper covers with no inner cover.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What were often found with a paper outter cover and no inner cover?
Ah, so.. Singles

Question: In June 2009 the first major building work at the abbey for 250 years was proposed. A coronaa crown-like architectural featurewas intended to be built around the lantern over the central crossing, replacing an existing pyramidal structure dating from the 1950s. This was part of a wider 23m development of the abbey expected to be completed in 2013. On 4 August 2010 the Dean and Chapter announced that, "[a]fter a considerable amount of preliminary and exploratory work", efforts toward the construction of a corona would not be continued. In 2012, architects Panter Hudspith completed refurbishment of the 14th-century food-store originally used by the abbey's monks, converting it into a restaurant with English Oak furniture by Covent Garden-based furniture makers Luke Hughes and Company.
Try to answer this question if possible: What was proposed for the abbey in June 2009?
Answer: major building work

Input: Read this: In 2003, additional UN sanctions were placed on Liberian timber exports, which had risen from US$5 million in 1997 to over US$100 million in 2002 and were believed to be funding rebels in Sierra Leone. These sanctions were lifted in 2006. Due in large part to foreign aid and investment inflow following the end of the war, Liberia maintains a large account deficit, which peaked at nearly 60% in 2008. Liberia gained observer status with the World Trade Organization in 2010 and is in the process of acquiring full member status.
Question: When were the timber export sanctions lifted for Liberia?

Output:
in 2006
