Passage: The book was written for non-specialist readers and attracted widespread interest upon its publication. As Darwin was an eminent scientist, his findings were taken seriously and the evidence he presented generated scientific, philosophical, and religious discussion. The debate over the book contributed to the campaign by T. H. Huxley and his fellow members of the X Club to secularise science by promoting scientific naturalism. Within two decades there was widespread scientific agreement that evolution, with a branching pattern of common descent, had occurred, but scientists were slow to give natural selection the significance that Darwin thought appropriate. During "the eclipse of Darwinism" from the 1880s to the 1930s, various other mechanisms of evolution were given more credit. With the development of the modern evolutionary synthesis in the 1930s and 1940s, Darwin's concept of evolutionary adaptation through natural selection became central to modern evolutionary theory, and it has now become the unifying concept of the life sciences. Question: What was T.H. Huxley promoting?
scientific naturalism

Passage: On November 13, 1988, approximately 10,000 people attended an officially sanctioned meeting organized by the cultural heritage organization Spadschyna, the Kyiv University student club Hromada, and the environmental groups Zelenyi Svit ("Green World") and Noosfera, to focus on ecological issues.

Passage: Because of his ability to motivate nationalistic passions, "men, women, and children wept and wailed in the streets" after hearing of his death, according to Nutting. The general Arab reaction was one of mourning, with thousands of people pouring onto the streets of major cities throughout the Arab world. Over a dozen people were killed in Beirut as a result of the chaos, and in Jerusalem, roughly 75,000 Arabs marched through the Old City chanting, "Nasser will never die." As a testament to his unchallenged leadership of the Arab people, following his death, the headline of the Lebanese Le Jour read, "One hundred million human beingsthe Arabsare orphans." Sherif Hetata, a former political prisoner and later member Nasser's ASU, said that "Nasser's greatest achievement was his funeral. The world will never again see five million people crying together." Question: What did a Lebanese publication call the Arabs following Nasser's death?
orphans
