Article: Whitehead was unimpressed by this objection. In the notes of one his students for a 1927 class, Whitehead was quoted as saying: "Every scientific man in order to preserve his reputation has to say he dislikes metaphysics. What he means is he dislikes having his metaphysics criticized." In Whitehead's view, scientists and philosophers make metaphysical assumptions about how the universe works all the time, but such assumptions are not easily seen precisely because they remain unexamined and unquestioned. While Whitehead acknowledged that "philosophers can never hope finally to formulate these metaphysical first principles," he argued that people need to continually re-imagine their basic assumptions about how the universe works if philosophy and science are to make any real progress, even if that progress remains permanently asymptotic. For this reason Whitehead regarded metaphysical investigations as essential to both good science and good philosophy.

Question: What did Whitehead feel was necessary regarding basic assumptions in metaphysics?
Ans: people need to continually re-imagine their basic assumptions about how the universe works if philosophy and science are to make any real progress

Here is a question about this article: A broad operational definition is sometimes used to encompass the complexity of these diverse phenomena, where a gene is defined as a union of genomic sequences encoding a coherent set of potentially overlapping functional products. This definition categorizes genes by their functional products (proteins or RNA) rather than their specific DNA loci, with regulatory elements classified as gene-associated regions.
What is the answer to this question: What does the broad operational definition of a gene classify as gene-associated regions?

The Palacio do Planalto is the official workplace of the President of Brazil. It is located at the Praca dos Tres Poderes in Brasilia. As the seat of government, the term "Planalto" is often used as a metonym for the executive branch of government. The main working office of the President of the Republic is in the Palacio do Planalto. The President and his or her family do not live in it, rather in the official residence, the Palacio da Alvorada.

The problem: Answer a question about this article:
Gaddafi remained a controversial and divisive figure on the world stage throughout his life and after death. Supporters praised Gaddafi's administration for the creation of an almost classless society through domestic reform. They stress the regime's achievements in combating homelessness and ensuring access to food and safe drinking water. Highlighting that under Gaddafi, all Libyans enjoyed free education to a university level, they point to the dramatic rise in literacy rates after the 1969 revolution. Supporters have also applauded achievements in medical care, praising the universal free healthcare provided under the Gaddafist administration, with diseases like cholera and typhoid being contained and life expectancy raised. Biographers Blundy and Lycett believed that under the first decade of Gaddafi's leadership, life for most Libyans "undoubtedly changed for the better" as material conditions and wealth drastically improved, while Libyan studies specialist Lillian Craig Harris remarked that in the early years of his administration, Libya's "national wealth and international influence soared, and its national standard of living has risen dramatically." Such high standards declined during the 1980s, as a result of economic stagnation. Gaddafi claimed that his Jamahiriya was a "concrete utopia", and that he had been appointed by "popular assent", with some Islamic supporters believing that he exhibited barakah. His opposition to Western governments earned him the respect of many in the Euro-American far right.
What was the cost of primary and secondary education under Gaddafi?
****
The answer:
