In a tumbling pass, dismount or vault, landing is the final phase, following take off and flight  This is a critical skill in terms of execution in competition scores, general performance, and injury occurrence. Without the necessary magnitude of energy dissipation during impact, the risk of sustaining injuries during somersaulting increases. These injuries commonly occur at the lower extremities such as: cartilage lesions, ligament tears, and bone bruises/fractures. To avoid such injuries, and to receive a high performance score, proper technique must be used by the gymnast. "The subsequent ground contact or impact landing phase must be achieved using a safe, aesthetic and well-executed double foot landing."  A successful landing in gymnastics is classified as soft, meaning the knee and hip joints are at greater than 63 degrees of flexion.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is a successful landing?
Ah, so.. soft, meaning the knee and hip joints are at greater than 63 degrees of flexion

Mass production of glass window panes in the early twentieth century caused a similar effect. In glass factories, molten glass was poured onto a large cooling table and allowed to spread. The resulting glass is thicker at the location of the pour, located at the center of the large sheet. These sheets were cut into smaller window panes with nonuniform thickness, typically with the location of the pour centered in one of the panes (known as "bull's-eyes") for decorative effect. Modern glass intended for windows is produced as float glass and is very uniform in thickness.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In early 20th century glass production, the glass was thickest at what part of the sheet?
Ah, so.. the center

Western commentators post-9/11 often perceive madaris as places of radical revivalism with a connotation of anti-Americanism and radical extremism, frequently associated in the Western press with Wahhabi attitudes toward non-Muslims. In Arabic the word madrasa simply means "school" and does not imply a political or religious affiliation, radical or otherwise. Madaris have varied curricula, and are not all religious. Some madaris in India, for example, have a secularised identity. Although early madaris were founded primarily to gain "knowledge of God" they also taught subjects such as mathematics and poetry. For example, in the Ottoman Empire, "Madrasahs had seven categories of sciences that were taught, such as: styles of writing, oral sciences like the Arabic language, grammar, rhetoric, and history and intellectual sciences, such as logic." This is similar to the Western world, in which universities began as institutions of the Catholic church.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is the common northern perception of the teaching received at madaris?
Ah, so..
