Problem: Before the advent of the ASA system, the system of Weston film speed ratings was introduced by Edward Faraday Weston (18781971) and his father Dr. Edward Weston (18501936), a British-born electrical engineer, industrialist and founder of the US-based Weston Electrical Instrument Corporation, with the Weston model 617, one of the earliest photo-electric exposure meters, in August 1932. The meter and film rating system were invented by William Nelson Goodwin, Jr., who worked for them and later received a Howard N. Potts Medal for his contributions to engineering.
What company did Dr. Edward Weston start?
The answer is the following: the US-based Weston Electrical Instrument Corporation

Problem: Italian unification was the political and social movement that annexed different states of the Italian peninsula into the single state of Italy in the 19th century. There is a lack of consensus on the exact dates for the beginning and the end of this period, but many scholars agree that the process began with the end of Napoleonic rule and the Congress of Vienna in 1815, and approximately ended with the Franco-Prussian War in 1871, though the last citta irredente did not join the Kingdom of Italy until after World War I.
What is Italian Unification?
The answer is the following: social movement that annexed different states of the Italian peninsula into the single state of Italy

Problem: The output of goods and services produced by labor and property located in the United Statesdecreased at an annual rate of approximately 6% in the fourth quarter of 2008 and first quarter of 2009, versus activity in the year-ago periods. The U.S. unemployment rate increased to 10.1% by October 2009, the highest rate since 1983 and roughly twice the pre-crisis rate. The average hours per work week declined to 33, the lowest level since the government began collecting the data in 1964. With the decline of gross domestic product came the decline in innovation. With fewer resources to risk in creative destruction, the number of patent applications flat-lined. Compared to the previous 5 years of exponential increases in patent application, this stagnation correlates to the similar drop in GDP during the same time period.
The U.E. employment rate was 10.2% in October 2009, which was the highest rate since what year?
The answer is the following: 1983

Problem: The length and nature of parental care varies widely amongst different orders and species. At one extreme, parental care in megapodes ends at hatching; the newly hatched chick digs itself out of the nest mound without parental assistance and can fend for itself immediately. At the other extreme, many seabirds have extended periods of parental care, the longest being that of the great frigatebird, whose chicks take up to six months to fledge and are fed by the parents for up to an additional 14 months. The chick guard stage describes the period of breeding during which one of the adult birds is permanently present at the nest after chicks have hatched. The main purpose of the guard stage is to aid offspring to thermoregulate and protect them from predation.
What type of seabird has the longest period of parental care?
The answer is the following:
frigatebird
