instruction:
In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
question:
What ties together spiritual leader and editor?, Context: According to the New Jersey Press Association, several media entities refrain from using the term "ultra-Orthodox", including the Religion Newswriters Association; JTA, the global Jewish news service; and the Star-Ledger, New Jersey's largest daily newspaper. The Star-Ledger was the first mainstream newspaper to drop the term. Several local Jewish papers, including New York's Jewish Week and Philadelphia's Jewish Exponent have also dropped use of the term. According to Rabbi Shammai Engelmayer, spiritual leader of Temple Israel Community Center in Cliffside Park and former executive editor of Jewish Week, this leaves "Orthodox" as "an umbrella term that designates a very widely disparate group of people very loosely tied together by some core beliefs."
answer:
Rabbi Shammai Engelmayer

question:
Which ship is older, the America, or the Enterprise?, Context: With the deactivation of USS Enterprise in December 2012, the U.S. fleet comprises 10 supercarriers. The House Armed Services Seapower subcommittee on 24 July 2007, recommended seven or maybe eight new carriers (one every four years). However, the debate has deepened over budgeting for the $1214.5 billion (plus $12 billion for development and research) for the 100,000 ton Gerald R. Ford-class carrier (estimated service 2016) compared to the smaller $2 billion 45,000 ton America-class amphibious assault ships, which are able to deploy squadrons of F-35Bs. The first of this class, USS America, is now in active service with another, USS Tripoli, under construction and 9 more are planned.
answer:
Enterprise

question:
What scientific process are scientists using unravel the link between genes and hair color?, Context: Mammalian hair, also known as pelage, can vary in color between populations, organisms within a population, and even on the individual organism. Light-dark color variation is common in the mammalian taxa. Sometimes, this color variation is determined by age variation, however, in other cases, it is determined by other factors. Selective pressures, such as ecological interactions with other populations or environmental conditions, often lead to the variation in mammalian coloration. These selective pressures favor certain colors in order to increase survival. Camouflage is thought to be a major selection pressure shaping coloration in mammals, although there is also evidence that sexual selection, communication, and physiological processes may influence the evolution of coloration as well. Camouflage is the most predominant mechanism for color variation, as it aids in the concealment of the organisms from predators or from their prey. Coat color can also be for intraspecies communication such as warning members of their species about predators, indicating health for reproductive purposes, communicating between mother and young, and intimidating predators. Studies have shown that in some cases, differences in female and male coat color could indicate information nutrition and hormone levels, which are important in the mate selection process. One final mechanism for coat color variation is physiological response purposes, such as temperature regulation in tropical or arctic environments. Although much has been observed about color variation, much of the genetic that link coat color to genes is still unknown. The genetic sites where pigmentation genes are found are known to affect phenotype by: 1) altering the spatial distribution of pigmentation of the hairs, and 2) altering the density and distribution of the hairs. Quantitative trait mapping is being used to better understand the distribution of loci responsible for pigmentation variation. However, although the genetic sites are known, there is still much to learn about how these genes are expressed.
answer:
Quantitative trait mapping
