Input: Consider Input: Question: Who designed Hans Klemm's first light aircraft? Passage:Hans Klemm's first light aircraft was the Daimler L15 and the L20 had much in common with it. Both were cantilever monoplanes with twin open, tandem cockpits and engines of very low power. The L20's low wing distinguished it from its predecessor and had the advantage of providing a low centre of gravity and better view during the landing approach as well as better protection for occupants in case of crash landings. The low-set wing also allowed a shorter undercarriage on the L20, which was otherwise like that of the L15 with the wheels independently mounted on pairs of centrally hinged V-struts and with vertical shock absorbing legs to the wing underside. Wheels were sometimes replaced by floats. Intended from the start for serial production, the L20's structure was simplified, with a pentagonal cross-section fuselage lacking the L15's rounded upper and lower surfaces. The fuselage was wooden framed with canvas covering. The overall strength of the structure, which had a safety factor of 12, was emphasised.

Input: Consider Input: Question: What is the official IAU name for the main star that is ioninizing  the surrounding material? Passage:Sharpless 264, also known as the Lambda Orionis Ring, is a molecular cloud and H II region, which can be seen in the northern region of the Orion Molecular Cloud Complex (OMCC), in the constellation of Orion. The OMCC is one of the best-known star formation regions and the closest sector of the Milky Way to our Solar System where high-mass stars are born. The nebula is named after its main star, λ Orionis, a blue giant responsible for the ionization of the surrounding material. It is also sometimes called the Angelfish Nebula due to its resemblance as to its lighter areas (pink to peach colour) to an angelfish. In the infrared its ionized boundaries are that which appears, instead.

Input: Consider Input: Question: What was the document that made India an officially secular nation ratified? Passage:India's present syncretic culture is reflected in the fused Hindu-muslim spiritual connotations, forms, symbols, aesthetics, crafts and weaves, for example Kashmiri muslim carpet makers feature Durga in their patterns, muslim sculptors making idols of Durga, and Hindu craftsmen create the Muharram tazia. This religious syncretism is a fusion of Hindu cultural elements with Muslim religious elements. It is based on the vasudhaiva kutumbakam, unity in diversity, multi-communitarianism and ganga-jamuni tehzeeb, It is born out of centuries of interfaith exchange and accommodation among Indian origin religions (Hindu, Buddhist, Jain, Sikh) and foreign origin religions (Muslim and Christian) where communities preserve own cultural and religious identities while facilitating the shared celebration of festivals, customs and traditions. In this syncretic culture, the shared Indian national identity is separated from the personal religious identity, and the nation and common social good comes first above the personal religion. Despite the partition of India, and resulting creation of Pakistan based on the concept of separate islamic nation for domination of muslims, this composite multiculturalism is integral to the present society of India. India is officially a secular nation, a concept legalised in the constitution of India. Contrastingly, constitution of Pakistan has Islam as its state religion, teaching of quran and islamiyat is compulsary,Constitution of Pakistan: Constitution of Pakistan, 1973 – Article: 31 Islamic way of life, Article 31 No. 2, 1973, Retrieved 22 August 2018. only muslims can become Prime Minister or President of Pakistan and nonmuslims are not given equal rights, Ahmadia muslims having equal constitutional rights in India are legally persecuted in Pakistan and constitutionally banned from calling themselves Muslims.
