Problem: A molecular form called protonated molecular hydrogen (H+
3) is found in the interstellar medium, where it is generated by ionization of molecular hydrogen from cosmic rays. This charged ion has also been observed in the upper atmosphere of the planet Jupiter. The ion is relatively stable in the environment of outer space due to the low temperature and density. H+
3 is one of the most abundant ions in the Universe, and it plays a notable role in the chemistry of the interstellar medium. Neutral triatomic hydrogen H3 can only exist in an excited form and is unstable. By contrast, the positive hydrogen molecular ion (H+
2) is a rare molecule in the universe.
What generates protonated molecular hydrogen?
The answer is the following: ionization of molecular hydrogen from cosmic rays

Problem: Some of the cleaner energy facilities in Boston include the Allston green district, with three ecologically compatible housing facilities. Boston is also breaking ground on multiple green affordable housing facilities to help reduce the carbon footprint of the city while simultaneously making these initiatives financially available to a greater population. Boston's climate plan is updated every three years and was most recently modified in 2013. This legislature includes the Building Energy Reporting and Disclosure Ordinance, which requires the city's larger buildings to disclose their yearly energy and water use statistics and partake in an energy assessment every five years. These statistics are made public by the city, thereby increasing incentives for buildings to be more environmentally conscious.
Allston Green District is an example of what?
The answer is the following: cleaner energy facilities

Problem: Protestants can be differentiated according to how they have been influenced by important movements since the Reformation, today regarded as branches. Some of these movements have a common lineage, sometimes directly spawning individual denominations. Due to the earlier stated multitude of denominations, this section discusses only the largest denominational families, or branches, widely considered to be a part of Protestantism. These are, in alphabetical order: Adventist, Anglican, Baptist, Calvinist (Reformed), Lutheran, Methodist and Pentecostal. A small but historically significant Anabaptist branch is also discussed.
What created the differentiation of Protestant branches?
The answer is the following: how they have been influenced by important movements since the Reformation

Problem: The site of Richmond had been an important village of the Powhatan Confederacy, and was briefly settled by English colonists from Jamestown in 1609, and in 1610–1611. The present city of Richmond was founded in 1737. It became the capital of the Colony and Dominion of Virginia in 1780. During the Revolutionary War period, several notable events occurred in the city, including Patrick Henry's "Give me liberty or give me death" speech in 1775 at St. John's Church, and the passage of the Virginia Statute for Religious Freedom written by Thomas Jefferson. During the American Civil War, Richmond served as the capital of the Confederate States of America. The city entered the 20th century with one of the world's first successful electric streetcar systems, as well as a national hub of African-American commerce and culture, the Jackson Ward neighborhood.
Richmond was an important city of what confederacy? 
The answer is the following:
the Powhatan Confederacy
