Input: High-definition television
In the US, residents in the line of sight of television station broadcast antennas can receive free, over the air programming with a television set with an ATSC tuner (most sets sold since 2009 have this). This is achieved with a TV aerial, just as it has been since the 1940s except now the major network signals are broadcast in high definition (ABC, Fox, and Ion Television broadcast at 720p resolution; CBS, My Network TV, NBC, PBS, and The CW at 1080i). As their digital signals more efficiently use the broadcast channel, many broadcasters are adding multiple channels to their signals. Laws about antennas were updated before the change to digital terrestrial broadcasts. These new laws prohibit home owners' associations and city government from banning the installation of antennas.

Who do these laws prohibit from banning the installation of antennas?
Output: home owners' associations and city government


Input: Article: No archaeological evidence that indicates a settlement on the site of today′s city centre prior to the 12th century has been found so far. In antiquity, a Celtic oppidum stood on the Engehalbinsel (peninsula) north of Bern, fortified since the 2nd century BC (late La Tène period), thought to be one of the twelve oppida of the Helvetii mentioned by Caesar. During the Roman era, there was a Gallo-Roman vicus on the same site. The Bern zinc tablet has the name Brenodor ("dwelling of Breno"). In the Early Middle Ages, there was a settlement in Bümpliz, now a city district of Bern, some 4 km (2 mi) from the medieval city.

Now answer this question: When was the settlement in Bumpliz close to the medieval city?

Output: Early Middle Ages

The problem: Answer a question about this article:
The main crops grown are barley, wheat, buckwheat, rye, potatoes, and assorted fruits and vegetables. Tibet is ranked the lowest among China’s 31 provinces on the Human Development Index according to UN Development Programme data. In recent years, due to increased interest in Tibetan Buddhism, tourism has become an increasingly important sector, and is actively promoted by the authorities. Tourism brings in the most income from the sale of handicrafts. These include Tibetan hats, jewelry (silver and gold), wooden items, clothing, quilts, fabrics, Tibetan rugs and carpets. The Central People's Government exempts Tibet from all taxation and provides 90% of Tibet's government expenditures. However most of this investment goes to pay migrant workers who do not settle in Tibet and send much of their income home to other provinces.
From which area does tourism bring the most income?
****
The answer: sale of handicrafts


The problem: Answer a question about this article:
When World War II started, tonnage levels at the port decreased and shipping activities were suspended; however, the war did provide economic benefits for the city. Petrochemical refineries and manufacturing plants were constructed along the ship channel because of the demand for petroleum and synthetic rubber products by the defense industry during the war. Ellington Field, initially built during World War I, was revitalized as an advanced training center for bombardiers and navigators. The Brown Shipbuilding Company was founded in 1942 to build ships for the U.S. Navy during World War II. Due to the boom in defense jobs, thousands of new workers migrated to the city, both blacks and whites competing for the higher-paying jobs. President Roosevelt had established a policy of non-discrimination for defense contractors, and blacks gained some opportunities, especially in shipbuilding, although not without resistance from whites and increasing social tensions that erupted into occasional violence. Economic gains of blacks who entered defense industries continued in the postwar years.
What event cause shipping activities to be suspended?
****
The answer:
World War II
