Question: Humanism is a philosophical and ethical stance that emphasizes the value and agency of human beings, individually and collectively, and generally prefers critical thinking and evidence (rationalism, empiricism) over acceptance of dogma or superstition. The meaning of the term humanism has fluctuated according to the successive intellectual movements which have identified with it. Generally, however, humanism refers to a perspective that affirms some notion of human freedom and progress. In modern times, humanist movements are typically aligned with secularism, and today humanism typically refers to a non-theistic life stance centred on human agency and looking to science rather than revelation from a supernatural source to understand the world.
Is there an answer to this question: What does humanism condemn instead of turning to a spiritual or divine source?

Answer: unanswerable


Question: On the recovery side of the flight deck, the adaptation to the aircraft loadout is mirrored. Non-VTOL or conventional aircraft cannot decelerate on their own, and almost all carriers using them must have arrested-recovery systems (-BAR, e.g. CATOBAR or STOBAR) to recover their aircraft. Aircraft that are landing extend a tailhook that catches on arrestor wires stretched across the deck to bring themselves to a stop in a short distance. Post-WWII Royal Navy research on safer CATOBAR recovery eventually led to universal adoption of a landing area angled off axis to allow aircraft who missed the arresting wires to "bolt" and safely return to flight for another landing attempt rather than crashing into aircraft on the forward deck.
Is there an answer to this question: Why do almost all carriers using nonconventional aircraft have arrested-recovery systems?

Answer: unanswerable


Question: In 1238, King James I of Aragon, with an army composed of Aragonese, Catalans, Navarrese and crusaders from the Order of Calatrava, laid siege to Valencia and on 28 September obtained a surrender. Fifty thousand Moors were forced to leave. Poets such as Ibn al-Abbar and Ibn Amira mourned this exile from their beloved Valencia. After the Christian victory and the expulsion of the Muslim population the city was divided between those who had participated in the conquest, according to the testimony in the Llibre del Repartiment (Book of Distribution). James I granted the city new charters of law, the Furs of Valencia, which later were extended to the whole kingdom of Valencia. Thenceforth the city entered a new historical stage in which a new society and a new language developed, forming the basis of the character of the Valencian people as they are known today.
Is there an answer to this question: What ruler attacked Valencia in 1238?

Answer:
King James I of Aragon
