Input: Article: Polyols, compounds containing more than one alcohol functional group, generally interact with cupric salts. For example, copper salts are used to test for reducing sugars. Specifically, using Benedict's reagent and Fehling's solution the presence of the sugar is signaled by a color change from blue Cu(II) to reddish copper(I) oxide. Schweizer's reagent and related complexes with ethylenediamine and other amines dissolve cellulose. Amino acids form very stable chelate complexes with copper(II). Many wet-chemical tests for copper ions exist, one involving potassium ferrocyanide, which gives a brown precipitate with copper(II) salts.

Now answer this question: How is the presence of sugar shown by using Benedict's reagent and Fehling's solution?

Output: color change

Input: Article: Reacting to media criticism of Michelle Obama during the 2008 presidential election, Charles Kenzie Steele, Jr., CEO of the Southern Christian Leadership Conference said, "Why are they attacking Michelle Obama, and not really attacking, to that degree, her husband? Because he has no slave blood in him." He later claimed his comment was intended to be "provocative" but declined to expand on the subject. Former Secretary of State Condoleezza Rice (who was famously mistaken for a "recent American immigrant" by French President Nicolas Sarkozy), said "descendants of slaves did not get much of a head start, and I think you continue to see some of the effects of that." She has also rejected an immigrant designation for African Americans and instead prefers the term "black" or "white" .

Now answer this question: What does Condoleeza Rice prefer to term people as?

Output: "black" or "white"

Input: Article: In 2004, the first bike lane in the city was added to Orange Street, connecting East Rock Park and the East Rock neighborhood to downtown. Since then, bike lanes have also been added to sections of Howard Ave, Elm St, Dixwell Avenue, Water Street, Clinton Avenue and State Street. The city has created recommended bike routes for getting around New Haven, including use of the Canal Trail and the Orange Street lane. A bike map of the city entire can be seen here , and bike maps broken down by area here . As of the end of 2012, bicycle lanes have also been added in both directions on Dixwell Avenue along most of the street from downtown to the Hamden town line, as well as along Howard Avenue from Yale New Haven Hospital to City Point.

Now answer this question: How is it possible to located the direction of bike lanes within the city?

Output:
