Question: An additional 4.6 billion tonnes of uranium are estimated to be in sea water (Japanese scientists in the 1980s showed that extraction of uranium from sea water using ion exchangers was technically feasible). There have been experiments to extract uranium from sea water, but the yield has been low due to the carbonate present in the water. In 2012, ORNL researchers announced the successful development of a new absorbent material dubbed HiCap which performs surface retention of solid or gas molecules, atoms or ions and also effectively removes toxic metals from water, according to results verified by researchers at Pacific Northwest National Laboratory.
Try to answer this question if possible: The presence of what substance in fresh water has resulted in low yields when attempting to extract uranium?
Answer: unanswerable
Question: Many architects resisted modernism, finding it devoid of the decorative richness of historical styles. As the first generation of modernists began to die after WWII, a second generation of architects including Paul Rudolph, Marcel Breuer, and Eero Saarinen tried to expand the aesthetics of modernism with Brutalism, buildings with expressive sculptural facades made of unfinished concrete. But an even new younger postwar generation critiqued modernism and Brutalism for being too austere, standardized, monotone, and not taking into account the richness of human experience offered in historical buildings across time and in different places and cultures.

Answer: unanswerable
Question: A commandery consisted of a group of counties, and was headed by an Administrator. He was the top civil and military leader of the commandery and handled defense, lawsuits, seasonal instructions to farmers and recommendations of nominees for office sent annually to the capital in a quota system first established by Emperor Wu. The head of a large county of about 10,000 households was called a Prefect, while the heads of smaller counties were called Chiefs, and both could be referred to as Magistrates. A Magistrate maintained law and order in his county, registered the populace for taxation, mobilized commoners for annual corvee duties, repaired schools and supervised public works.

Answer: an Administrator
Question: In 1976, contemporaneously with Woodson and Roberts, the Court decided Gregg v. Georgia and upheld a procedure in which the trial of capital crimes was bifurcated into guilt-innocence and sentencing phases. At the first proceeding, the jury decides the defendant's guilt; if the defendant is innocent or otherwise not convicted of first-degree murder, the death penalty will not be imposed. At the second hearing, the jury determines whether certain statutory aggravating factors exist, whether any mitigating factors exist, and, in many jurisdictions, weigh the aggravating and mitigating factors in assessing the ultimate penalty either death or life in prison, either with or without parole.
Try to answer this question if possible: Along with aggravating factors, what other factors are considered at the third hearing?
