Example 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.

He attended the "Empress Augusta [secondary] school" ("Kaiserin-Augusta-Gymnasium" - as the "Ludwig-Cauer-Grundschule" was then known), and passed his school final exams ("Abitur") in 1909 which opened the way to a university education.

For his subsidiary module on Applied Economics he was taught by Gustav Schmoller. He received his doctorate in 1914 for work on the eleventh century Bishopric of Liège. The work was supervised by . However, after war broke out at the end of July 1914 there was a major falling out with Schäfer. The German High Command implemented war plans that included a rapid invasion of Belgium which was accompanied by persistent reports of widescale atrocities by German troops against Belgian civilians. Sproemberg was at pains to distance himself from Schäfer's "annexationist" support for German policy in respect of Belgium.
