An alloy of aluminium and gallium in pellet form added to water can be used to generate hydrogen. The process also produces alumina, but the expensive gallium, which prevents the formation of an oxide skin on the pellets, can be re-used. This has important potential implications for a hydrogen economy, as hydrogen can be produced on-site and does not need to be transported.
When you combine an alloy of alluminum and gallium to water, what do you get?
hydrogen

TCM's film content has remained mostly uncut and uncolorized (with films natively filmed or post-produced in the format being those only ones presented in color), depending upon the original content of movies, particularly movies released after the 1968 implementation of the Motion Picture Association of America's ratings system and the concurrent disestablishment of the Motion Picture Production Code. Because of this, TCM is formatted similarly to a premium channel with certain films particularly those made from the 1960s onward sometimes featuring nudity, sexual content, violence and/or strong profanity; the network also features rating bumpers prior to the start of a program (most programs on TCM, especially films, are rated for content using the TV Parental Guidelines, in lieu of the MPAA's rating system).

In what year did the Motion Picture Association of America introduce its rating system?
Output: 1968

Input: Article: The sovereign territory of Israel (according to the demarcation lines of the 1949 Armistice Agreements and excluding all territories captured by Israel during the 1967 Six-Day War) is approximately 20,770 square kilometers (8,019 sq mi) in area, of which two percent is water. However Israel is so narrow that the exclusive economic zone in the Mediterranean is double the land area of the country. The total area under Israeli law, including East Jerusalem and the Golan Heights, is 22,072 square kilometers (8,522 sq mi), and the total area under Israeli control, including the military-controlled and partially Palestinian-governed territory of the West Bank, is 27,799 square kilometers (10,733 sq mi). Despite its small size, Israel is home to a variety of geographic features, from the Negev desert in the south to the inland fertile Jezreel Valley, mountain ranges of the Galilee, Carmel and toward the Golan in the north. The Israeli Coastal Plain on the shores of the Mediterranean is home to 57 percent of the nation's population. East of the central highlands lies the Jordan Rift Valley, which forms a small part of the 6,500-kilometer (4,039 mi) Great Rift Valley.

Now answer this question: How big is the sovereign territory of Israel?

Output: 20,770 square kilometers

Article: In non-relativistic classical mechanics, Newton's concept of "relative, apparent, and common time" can be used in the formulation of a prescription for the synchronization of clocks. Events seen by two different observers in motion relative to each other produce a mathematical concept of time that works sufficiently well for describing the everyday phenomena of most people's experience. In the late nineteenth century, physicists encountered problems with the classical understanding of time, in connection with the behavior of electricity and magnetism. Einstein resolved these problems by invoking a method of synchronizing clocks using the constant, finite speed of light as the maximum signal velocity. This led directly to the result that observers in motion relative to one another measure different elapsed times for the same event.

Question: The behavior of which two phenomena caused physicists to encounter problems with their understanding of time in the late 19th century?
Ans: the behavior of electricity and magnetism

Here is a question about this article: Organisms inherit their genes from their parents. Asexual organisms simply inherit a complete copy of their parent's genome. Sexual organisms have two copies of each chromosome because they inherit one complete set from each parent.:1
What is the answer to this question: Where do organisms inherit their genes from?
****
So... from their parents

Article: Cladistics is another method of classification. A clade is a taxonomic group of organisms consisting of a single common ancestor and all the descendants of that ancestor. Every creature produced by sexual reproduction has two immediate lineages, one maternal and one paternal. Whereas Carl Linnaeus established a taxonomy of living organisms based on anatomical similarities and differences, cladistics seeks to establish a taxonomythe phylogenetic treebased on genetic similarities and differences and tracing the process of acquisition of multiple characteristics by single organisms. Some researchers have tried to clarify the idea of race by equating it to the biological idea of the clade. Often mitochondrial DNA or Y chromosome sequences are used to study ancient human migration paths. These single-locus sources of DNA do not recombine and are inherited from a single parent. Individuals from the various continental groups tend to be more similar to one another than to people from other continents, and tracing either mitochondrial DNA or non-recombinant Y-chromosome DNA explains how people in one place may be largely derived from people in some remote location.

Question: How many common ancestors does a clade have?
Ans:
single
