Input: Madonna (entertainer)
Madonna starred as Breathless Mahoney in the film Dick Tracy (1990), with Warren Beatty playing the title role. Her performance led to a Saturn Award nomination for Best Actress. To accompany the film, she released the soundtrack album, I'm Breathless, which included songs inspired by the film's 1930s setting. It also featured the US number-one hit "Vogue" and "Sooner or Later", which earned songwriter Stephen Sondheim an Academy Award for Best Original Song in 1991. While shooting the film, Madonna began a relationship with Beatty, which dissolved by the end of 1990. In April 1990, Madonna began her Blond Ambition World Tour, which was held until August. Rolling Stone called it an "elaborately choreographed, sexually provocative extravaganza" and proclaimed it "the best tour of 1990". The tour generated strong negative reaction from religious groups for her performance of "Like a Virgin", during which two male dancers caressed her body before she simulated masturbation. In response, Madonna said, "The tour in no way hurts anybody's sentiments. It's for open minds and gets them to see sexuality in a different way. Their own and others". The Laserdisc release of the tour won Madonna a Grammy Award in 1992 for Best Long Form Music Video.

When did Madonna and Beatty's relationship end?
Output: end of 1990

Input: Solar energy
Urban heat islands (UHI) are metropolitan areas with higher temperatures than that of the surrounding environment. The higher temperatures are a result of increased absorption of the Solar light by urban materials such as asphalt and concrete, which have lower albedos and higher heat capacities than those in the natural environment. A straightforward method of counteracting the UHI effect is to paint buildings and roads white and plant trees. Using these methods, a hypothetical "cool communities" program in Los Angeles has projected that urban temperatures could be reduced by approximately 3 °C at an estimated cost of US$1 billion, giving estimated total annual benefits of US$530 million from reduced air-conditioning costs and healthcare savings.

A program in Los Angeles believes that with $1 billion, city temperatures could be reduced by approximately how many degrees in Celsius?
Output: 3

Input: Chihuahua (state)
The liberal political forces maintained strong control over the state government until shortly after the French Intervention which turned the tables in favor to the conservative forces once again. The intervention had serious repercussions for the state of Chihuahua. President Juárez, in an effort to organize a strong defense against the French, decreed a list of national guard units that every state had to contribute to the Ministry of War and the Navy; Chihuahua was responsible for inducting 2,000 men. Regaining power, Governor Luis Terrazas assigned the First Battalion of Chihuahua for integration into the national army led by General Jesús González Ortega; the battalion was deployed to Puebla. After the defeat of the army in Puebla, the Juárez administration was forced to abandon Mexico City; the president retreated further north seeking refuge in the state of Chihuahua.

Governor Luis Terrazas
