Problem: New Haven, Connecticut:

The Farmington Canal Trail is a rail trail that will eventually run continuously from downtown New Haven to Northampton, Massachusetts. The scenic trail follows the path of the historic New Haven and Northampton Company and the Farmington Canal. Currently, there is a continuous 14-mile (23 km) stretch of the trail from downtown, through Hamden and into Cheshire, making bicycle commuting between New Haven and those suburbs possible. The trail is part of the East Coast Greenway, a proposed 3,000-mile (4,800 km) bike path that would link every major city on the East Coast from Florida to Maine.

What historic trail does the Farmington Canal Trail follow?

A: New Haven and Northampton Company


Problem: Multiracial American:

After a lengthy period of formal racial segregation in the former Confederacy following the Reconstruction Era, and bans on interracial marriage in various parts of the country, more people are openly forming interracial unions. In addition, social conditions have changed and many multiracial people do not believe it is socially advantageous to try to "pass" as white. Diverse immigration has brought more mixed-race people into the United States, such as the large population of Hispanics identifying as mestizos. Since the 1980s, the United States has had a growing multiracial identity movement (cf. Loving Day). Because more Americans have insisted on being allowed to acknowledge their mixed racial origins, the 2000 census for the first time allowed residents to check more than one ethno-racial identity and thereby identify as multiracial. In 2008 Barack Obama was elected as the first multiracial President of the United States; he acknowledges both sides of his family and identifies as African American.

When did the US begin to experience a growing multiracial identity movement?

A: Since the 1980s, the United States has had a growing multiracial identity movement

Problem: Space Race:

The trip to the Moon took just over three days. After achieving orbit, Armstrong and Aldrin transferred into the Lunar Module, named Eagle, and after a landing gear inspection by Collins remaining in the Command/Service Module Columbia, began their descent. After overcoming several computer overload alarms caused by an antenna switch left in the wrong position, and a slight downrange error, Armstrong took over manual flight control at about 180 meters (590 ft), and guided the Lunar Module to a safe landing spot at 20:18:04 UTC, July 20, 1969 (3:17:04 pm CDT). The first humans on the Moon would wait another six hours before they ventured out of their craft. At 02:56 UTC, July 21 (9:56 pm CDT July 20), Armstrong became the first human to set foot on the Moon.

How long did the trip to the Moon last for the crew of the Apollo 11?
