In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
question:
The top is held in place with?, Context: Inner and outer vestibules lead to the octagonal chapter house, which is of exceptional architectural purity. It is built in a Geometrical Gothic style with an octagonal crypt below. A pier of eight shafts carries the vaulted ceiling. To the sides are blind arcading, remains of 14th-century paintings and numerous stone benches above which are innovatory large 4-light quatre-foiled windows. These are virtually contemporary with the Sainte-Chapelle, Paris.
answer:
eight shafts


question:
Which of the following is not explicitly conservationist: Theodore Roosevelt, Pheasants Forever, or the Boone and Crockett Club?, Context: Regulation of hunting within the United States dates from the 19th century. Some modern hunters see themselves as conservationists and sportsmen in the mode of Theodore Roosevelt and the Boone and Crockett Club. Local hunting clubs and national organizations provide hunter education and help protect the future of the sport by buying land for future hunting use. Some groups represent a specific hunting interest, such as Ducks Unlimited, Pheasants Forever, or the Delta Waterfowl Foundation. Many hunting groups also participate in lobbying the federal government and state government.
answer:
Pheasants Forever


question:
What is the recipe for protein?, Context: Genes can acquire mutations in their sequence, leading to different variants, known as alleles, in the population. These alleles encode slightly different versions of a protein, which cause different phenotype traits. Colloquial usage of the term "having a gene" (e.g., "good genes," "hair colour gene") typically refers to having a different allele of the gene. Genes evolve due to natural selection or survival of the fittest of the alleles.
answer:

alleles
