Problem: On the uneven bars, the gymnast performs a routine on two horizontal bars set at different heights. These bars are made of fiberglass covered in wood laminate, to prevent them from breaking. In the past, bars were made of wood, but the bars were prone to breaking, providing an incentive to switch to newer technologies. The width and height of the bars may be adjusted. In the past, the uneven parallel bars were closer together. They've been moved increasingly further apart, allowing gymnasts to perform swinging, circling, transitional, and release moves, that may pass over, under, and between the two bars. At the Elite level, movements must pass through the handstand. Gymnasts often mount the Uneven Bars using a springboard, or a small mat. Chalk and grips (a leather strip with holes for fingers to protect hands and improve performance) may be used while doing this event. The chalk helps take the moisture out of gymnast's hands to decrease friction and prevent rips (tears to the skin of the hands), dowel grips help gymnasts grip the bar.

Problem: Nearly all polychaetes have parapodia that function as limbs, while other major annelid groups lack them. Parapodia are unjointed paired extensions of the body wall, and their muscles are derived from the circular muscles of the body. They are often supported internally by one or more large, thick chetae. The parapodia of burrowing and tube-dwelling polychaetes are often just ridges whose tips bear hooked chetae. In active crawlers and swimmers the parapodia are often divided into large upper and lower paddles on a very short trunk, and the paddles are generally fringed with chetae and sometimes with cirri (fused bundles of cilia) and gills.
What kind of parapodia do burrowing annelids often have?

Answer: ridges whose tips bear hooked chetae

Problem: But in the mid-18th century, during the French Enlightenment, a more ideological use of the term had come into use. In 1765, the author of an anonymous article in a French Enlightenment periodical spoke of "The general love of humanity ... a virtue hitherto quite nameless among us, and which we will venture to call 'humanism', for the time has come to create a word for such a beautiful and necessary thing". The latter part of the 18th and the early 19th centuries saw the creation of numerous grass-roots "philanthropic" and benevolent societies dedicated to human betterment and the spreading of knowledge (some Christian, some not). After the French Revolution, the idea that human virtue could be created by human reason alone independently from traditional religious institutions, attributed by opponents of the Revolution to Enlightenment philosophes such as Rousseau, was violently attacked by influential religious and political conservatives, such as Edmund Burke and Joseph de Maistre, as a deification or idolatry of humanity. Humanism began to acquire a negative sense. The Oxford English Dictionary records the use of the word "humanism" by an English clergyman in 1812 to indicate those who believe in the "mere humanity" (as opposed to the divine nature) of Christ, i.e., Unitarians and Deists. In this polarised atmosphere, in which established ecclesiastical bodies tended to circle the wagons and reflexively oppose political and social reforms like extending the franchise, universal schooling, and the like, liberal reformers and radicals embraced the idea of Humanism as an alternative religion of humanity. The anarchist Proudhon (best known for declaring that "property is theft") used the word "humanism" to describe a "culte, deification de l'humanite" ("worship, deification of humanity") and Ernest Renan in L'avenir de la science: pensees de 1848 ("The Future of Knowledge: Thoughts on 1848") (184849), states: "It is my deep conviction that pure humanism will be the religion of the future, that is, the cult of all that pertains to humanityall of life, sanctified and raised to the level of a moral value."
