Problem: Child labour:

Work is undertaken from an early age by vast numbers of children in the world and may have a natural place in growing up. Work can contribute to the well-being of children in a variety of ways; children often choose to work to improve their lives, both in the short- and long-term. At the material level, children's work often contributes to producing food or earning income that benefits themselves and their families; and such income is especially important when the families are poor. Work can provide an escape from debilitating poverty, sometimes by allowing a young person to move away from an impoverished environment. Young people often enjoy their work, especially paid work, or when work involves the company of peers. Even when work is intensive and enforced, children often find ways to combine their work with play.

What is an escape for the young that live in poverty?

A: Work

Problem: In 1976 John Goldsmith introduced autosegmental phonology. Phonological phenomena are no longer seen as operating on one linear sequence of segments, called phonemes or feature combinations, but rather as involving some parallel sequences of features which reside on multiple tiers. Autosegmental phonology later evolved into feature geometry, which became the standard theory of representation for theories of the organization of phonology as different as lexical phonology and optimality theory.
What did Autosegmental phonology morph into?
---
Answer: feature geometry

Context and question: Forest gardening was also being used as a food production system in various parts of the world over this period. Forest gardens originated in prehistoric times along jungle-clad river banks and in the wet foothills of monsoon regions.[citation needed] In the gradual process of families improving their immediate environment, useful tree and vine species were identified, protected and improved, whilst undesirable species were eliminated. Eventually superior foreign species were selected and incorporated into the gardens.
When families were trying to ruin their immediate environment, undesirable species were what?
Answer: unanswerable

Question: The Lobund Institute grew out of pioneering research in germ-free-life which began in 1928. This area of research originated in a question posed by Pasteur as to whether animal life was possible without bacteria. Though others had taken up this idea, their research was short lived and inconclusive. Lobund was the first research organization to answer definitively, that such life is possible and that it can be prolonged through generations. But the objective was not merely to answer Pasteur's question but also to produce the germ free animal as a new tool for biological and medical research. This objective was reached and for years Lobund was a unique center for the study and production of germ free animals and for their use in biological and medical investigations. Today the work has spread to other universities. In the beginning it was under the Department of Biology and a program leading to the master's degree accompanied the research program. In the 1940s Lobund achieved independent status as a purely research organization and in 1950 was raised to the status of an Institute. In 1958 it was brought back into the Department of Biology as integral part of that department, but with its own program leading to the degree of PhD in Gnotobiotics.
Is there an answer to this question: In what year did Lobund at Notre Dame become an Institute?

Answer: 1950

Question: METRO began light rail service on January 1, 2004, with the inaugural track ("Red Line") running about 8 miles (13 km) from the University of HoustonDowntown (UHD), which traverses through the Texas Medical Center and terminates at NRG Park. METRO is currently in the design phase of a 10-year expansion plan that will add five more lines. and expand the current Red Line. Amtrak, the national passenger rail system, provides service three times a week to Houston via the Sunset Limited (Los AngelesNew Orleans), which stops at a train station on the north side of the downtown area. The station saw 14,891 boardings and alightings in fiscal year 2008. In 2012, there was a 25 percent increase in ridership to 20,327 passengers embarking from the Houston Amtrak station.
Is there an answer to this question: When did Houston start using light rail lines?

Answer:
January 1, 2004
