Input: Read this: Another misunderstanding is that, by her immaculate conception, Mary did not need a saviour. When defining the dogma in Ineffabilis Deus, Pope Pius IX explicitly affirmed that Mary was redeemed in a manner more sublime. He stated that Mary, rather than being cleansed after sin, was completely prevented from contracting Original Sin in view of the foreseen merits of Jesus Christ, the Savior of the human race. In Luke 1:47, Mary proclaims: "My spirit has rejoiced in God my Saviour." This is referred to as Mary's pre-redemption by Christ. Since the Second Council of Orange against semi-pelagianism, the Catholic Church has taught that even had man never sinned in the Garden of Eden and was sinless, he would still require God's grace to remain sinless.
Question: What did Mary supposedly not require that everyone else also required and why was this so ?

Output: Another misunderstanding is that, by her immaculate conception, Mary did not need a saviour


Input: Read this: More complex inflection is still found in certain lexicalized expressions like de heer des huizes (literally, the man of the house), etc. These are usually remnants of cases (in this instance, the genitive case which is still used in German, cf. Der Herr des Hauses) and other inflections no longer in general use today. In such lexicalized expressions remnants of strong and weak nouns can be found too, e.g. in het jaar des Heren (Anno Domini), where "-en" is actually the genitive ending of the weak noun. Also in this case, German retains this feature. Though the genitive is widely avoided in speech.
Question: What case no longer used in Dutch is still present in German phrases like "Der Herr des Hauses"?

Output: genitive


Input: Read this: The Yoga school builds on the Samkhya school theory that jñāna (knowledge) is a sufficient means to moksha. It suggests that systematic techniques/practice (personal experimentation) combined with Samkhya's approach to knowledge is the path to moksha. Yoga shares several central ideas with Advaita Vedanta, with the difference that Yoga is a form of experimental mysticism while Advaita Vedanta is a form of monistic personalism. Like Advaita Vedanta, the Yoga school of Hindu philosophy states that liberation/freedom in this life is achievable, and this occurs when an individual fully understands and realizes the equivalence of Atman (soul, self) and Brahman.
Question: What is Brahaman?

Output: unanswerable


Input: Read this: There are a number of aids available to pilots, though not all airports are equipped with them. A visual approach slope indicator (VASI) helps pilots fly the approach for landing. Some airports are equipped with a VHF omnidirectional range (VOR) to help pilots find the direction to the airport. VORs are often accompanied by a distance measuring equipment (DME) to determine the distance to the VOR. VORs are also located off airports, where they serve to provide airways for aircraft to navigate upon. In poor weather, pilots will use an instrument landing system (ILS) to find the runway and fly the correct approach, even if they cannot see the ground. The number of instrument approaches based on the use of the Global Positioning System (GPS) is rapidly increasing and may eventually be the primary means for instrument landings.
Question: What helps pilots fly the approach for landing?

Output:
visual approach slope indicator
