Problem: Manhattan Island is linked to New York City's outer boroughs and New Jersey by several tunnels as well. The Lincoln Tunnel, which carries 120,000 vehicles a day under the Hudson River between New Jersey and Midtown Manhattan, is the busiest vehicular tunnel in the world. The tunnel was built instead of a bridge to allow unfettered passage of large passenger and cargo ships that sailed through New York Harbor and up the Hudson River to Manhattan's piers. The Holland Tunnel, connecting Lower Manhattan to Jersey City, New Jersey, was the world's first mechanically ventilated vehicular tunnel when it opened in 1927. The Queens-Midtown Tunnel, built to relieve congestion on the bridges connecting Manhattan with Queens and Brooklyn, was the largest non-federal project in its time when it was completed in 1940. President Franklin D. Roosevelt was the first person to drive through it. The Hugh L. Carey Tunnel runs underneath Battery Park and connects the Financial District at the southern tip of Manhattan to Red Hook in Brooklyn.
The Queens-Midtown Tunnel was finished in what year?
The answer is the following: 1940

Problem: A further complication is that the measurement of γ′p involves the measurement of an electric current: this is invariably measured in conventional amperes rather than in SI amperes, so a conversion factor is required. The symbol Γ′p-90 is used for the measured gyromagnetic ratio using conventional electrical units. In addition, there are two methods of measuring the value, a "low-field" method and a "high-field" method, and the conversion factors are different in the two cases. Only the high-field value Γ′p-90(hi) is of interest in determining the Planck constant.
Why is the measurement of electric current an issue in the estimate of the gyromagnetic ratio?
The answer is the following: electric current: this is invariably measured in conventional amperes rather than in SI amperes

Problem: In 2013 tourism within the state from local citizens accounted for 39.9% of tourists, the second highest originating location for tourists to Tennessee is the state of Georgia, accounting for 8.4% of tourists.:17 Forty-four percent of stays in the state were "day trips", 25% stayed one night, 15% stayed two nights, and 11% stayed 4 or more nights. The average stay was 2.16 nights, compared to 2.03 nights for the US as a whole.:40 The average person spent $118 per day: 29% on transportation, 24% on food, 17% on accommodation, and 28% on shopping and entertainment.:44
What average daily amount did a tourist spend in Tennessee in 2013?
The answer is the following: $118

Problem: Some copyright owners voluntarily reduce the scope of what is considered infringement by employing relatively permissive, "open" licensing strategies: rather than privately negotiating license terms with individual users who must first seek out the copyright owner and ask for permission, the copyright owner publishes and distributes the work with a prepared license that anyone can use, as long as they adhere to certain conditions. This has the effect of reducing infringement – and the burden on courts – by simply permitting certain types of uses under terms that the copyright owner considers reasonable. Examples include free software licenses, like the GNU General Public License (GPL), and the Creative Commons licenses, which are predominantly applied to visual and literary works.
What do some copyright owners do by reducing the scope of infringement?
The answer is the following:
employing relatively permissive, "open" licensing
