TASK DEFINITION: In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
PROBLEM: What residential units have revitalized New Haven?, Context: Since approximately 2000, many parts of downtown New Haven have been revitalized, with new restaurants, nightlife, and small retail stores. In particular, the area surrounding the New Haven Green has experienced an influx of apartments and condominiums. In recent years, downtown retail options have increased with the opening of new stores such as Urban Oufitters, J Crew, Origins, American Apparel, Gant Clothing, and an Apple Store, joining older stores such as Barnes & Noble, Cutlers Records, and Raggs Clothing. In addition, downtown's growing residential population will be served by two new supermarkets, a Stop & Shop just outside downtown and Elm City Market located one block from the Green. The recent turnaround of downtown New Haven has received positive press from various periodicals.

SOLUTION: apartments and condominiums

PROBLEM: Which of the following is a type of DNA: junk, multicellular or dense?, Context: Whereas the chromosomes of prokaryotes are relatively gene-dense, those of eukaryotes often contain regions of DNA that serve no obvious function. Simple single-celled eukaryotes have relatively small amounts of such DNA, whereas the genomes of complex multicellular organisms, including humans, contain an absolute majority of DNA without an identified function. This DNA has often been referred to as "junk DNA". However, more recent analyses suggest that, although protein-coding DNA makes up barely 2% of the human genome, about 80% of the bases in the genome may be expressed, so the term "junk DNA" may be a misnomer.

SOLUTION: junk

PROBLEM: what machine is mentioned first?, Context: Eventually, when it was more common for electric recordings to be played back electrically in the 1930s and 1940s, the overall tone was much like listening to a radio of the era. Magnetic pickups became more common and were better designed as time went on, making it possible to improve the damping of spurious resonances. Crystal pickups were also introduced as lower cost alternatives. The dynamic or moving coil microphone was introduced around 1930 and the velocity or ribbon microphone in 1932. Both of these high quality microphones became widespread in motion picture, radio, recording, and public address applications.

SOLUTION:
radio
