Problem: On September 27, 2006 Schwarzenegger signed a bill creating the nation's first cap on greenhouse gas emissions. The law set new regulations on the amount of emissions utilities, refineries and manufacturing plants are allowed to release into the atmosphere. Schwarzenegger also signed a second global warming bill that prohibits large utilities and corporations in California from making long-term contracts with suppliers who do not meet the state's greenhouse gas emission standards. The two bills are part of a plan to reduce California's emissions by 25 percent to 1990s levels by 2020. In 2005, Schwarzenegger issued an executive order calling to reduce greenhouse gases to 80 percent below 1990 levels by 2050.
What year has Schwarzenegger set as the deadline for California to show a 25% reduction in emissions?

Answer: 2020

Problem: In 1972, Walter Fiers and his team at the University of Ghent were the first to determine the sequence of a gene: the gene for Bacteriophage MS2 coat protein. The subsequent development of chain-termination DNA sequencing in 1977 by Frederick Sanger improved the efficiency of sequencing and turned it into a routine laboratory tool. An automated version of the Sanger method was used in early phases of the Human Genome Project.
Who developed chain termination DNA sequencing in 1977?

Answer:
Frederick Sanger
