The problem: Answer a question about this article:
Matter commonly exists in four states (or phases): solid, liquid and gas, and plasma. However, advances in experimental techniques have revealed other previously theoretical phases, such as BoseEinstein condensates and fermionic condensates. A focus on an elementary-particle view of matter also leads to new phases of matter, such as the quarkgluon plasma. For much of the history of the natural sciences people have contemplated the exact nature of matter. The idea that matter was built of discrete building blocks, the so-called particulate theory of matter, was first put forward by the Greek philosophers Leucippus (~490 BC) and Democritus (~470380 BC).
People have been wondering about the nature of matter for the entire history of what branch of science?

The answer: natural sciences

Problem: Please answer a question about the following article about Age of Enlightenment:
Broadly speaking, Enlightenment science greatly valued empiricism and rational thought, and was embedded with the Enlightenment ideal of advancement and progress. The study of science, under the heading of natural philosophy, was divided into physics and a conglomerate grouping of chemistry and natural history, which included anatomy, biology, geology, mineralogy, and zoology. As with most Enlightenment views, the benefits of science were not seen universally; Rousseau criticized the sciences for distancing man from nature and not operating to make people happier. Science during the Enlightenment was dominated by scientific societies and academies, which had largely replaced universities as centres of scientific research and development. Societies and academies were also the backbone of the maturation of the scientific profession. Another important development was the popularization of science among an increasingly literate population. Philosophes introduced the public to many scientific theories, most notably through the Encyclopedie and the popularization of Newtonianism by Voltaire and Emilie du Chatelet. Some historians have marked the 18th century as a drab period in the history of science; however, the century saw significant advancements in the practice of medicine, mathematics, and physics; the development of biological taxonomy; a new understanding of magnetism and electricity; and the maturation of chemistry as a discipline, which established the foundations of modern chemistry.
Who criticized the sciences for distancing man from nature and not operating to make people happier?
A: Rousseau

In modern times, the Javanese are the largest ethnic group in Southeast Asia, with more than 100 million people, mostly concentrated in Java, Indonesia. In Burma, the Burmese account for more than two-thirds of the ethnic stock in this country, while ethnic Thais and Vietnamese account for about four-fifths of the respective populations of those countries. Indonesia is clearly dominated by the Javanese and Sundanese ethnic groups, while Malaysia is split between half Malays and one-quarter Chinese. Within the Philippines, the Tagalog, Cebuano, Ilocano, and Hiligaynon groups are significant.

The ethnic groups Malays & Chinese are predominant in which country?
Answer: Malaysia

Problem: In early 1991, non-Arabs of the Zaghawa tribe of Sudan attested that they were victims of an intensifying Arab apartheid campaign, segregating Arabs and non-Arabs (specifically people of sub-Saharan African descent). Sudanese Arabs, who controlled the government, were widely referred to as practicing apartheid against Sudan's non-Arab citizens. The government was accused of "deftly manipulat(ing) Arab solidarity" to carry out policies of apartheid and ethnic cleansing.
Who felt persecuted due to the apartheid?
The answer is the following: non-Arabs of the Zaghawa tribe

The Greeks of classical antiquity idealized their Mycenaean ancestors and the Mycenaean period as a glorious era of heroes, closeness of the gods and material wealth. The Homeric Epics (i.e. Iliad and Odyssey) were especially and generally accepted as part of the Greek past and it was not until the 19th century that scholars began to question Homer's historicity. As part of the Mycenaean heritage that survived, the names of the gods and goddesses of Mycenaean Greece (e.g. Zeus, Poseidon and Hades) became major figures of the Olympian Pantheon of later antiquity.
What literary events were believed to be a fact of truth ?
The Homeric Epics (i.e. Iliad and Odyssey) were especially and generally accepted as part of the Greek past

Here is a question about this article: A zygote initially develops into a hollow sphere, called a blastula, which undergoes rearrangement and differentiation. In sponges, blastula larvae swim to a new location and develop into a new sponge. In most other groups, the blastula undergoes more complicated rearrangement. It first invaginates to form a gastrula with a digestive chamber, and two separate germ layers an external ectoderm and an internal endoderm. In most cases, a mesoderm also develops between them. These germ layers then differentiate to form tissues and organs.
What is the answer to this question: What may be formed between the external ectoderm and an internal endoderm layers?
****
So...
mesoderm
