To continue evacuating a chamber indefinitely without requiring infinite growth, a compartment of the vacuum can be repeatedly closed off, exhausted, and expanded again. This is the principle behind positive displacement pumps, like the manual water pump for example. Inside the pump, a mechanism expands a small sealed cavity to create a vacuum. Because of the pressure differential, some fluid from the chamber (or the well, in our example) is pushed into the pump's small cavity. The pump's cavity is then sealed from the chamber, opened to the atmosphere, and squeezed back to a minute size.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Why is fluid in a manual pump pushed into the pumps cavity when a small sealed cavity is expanded?
Ah, so.. Because of the pressure differential

There are many names for God, and different names are attached to different cultural ideas about God's identity and attributes. In the ancient Egyptian era of Atenism, possibly the earliest recorded monotheistic religion, this deity was called Aten, premised on being the one "true" Supreme Being and Creator of the Universe. In the Hebrew Bible and Judaism, "He Who Is", "I Am that I Am", and the tetragrammaton YHWH are used as names of God, while Yahweh and Jehovah are sometimes used in Christianity as vocalizations of YHWH. In the Christian doctrine of the Trinity, God, consubstantial in three persons, is called the Father, the Son, and the Holy Spirit. In Judaism, it is common to refer to God by the titular names Elohim or Adonai, the latter of which is believed by some scholars to descend from the Egyptian Aten. In Islam, the name Allah, "Al-El", or "Al-Elah" ("the God") is used, while Muslims also have a multitude of titular names for God. In Hinduism, Brahman is often considered a monistic deity. Other religions have names for God, for instance, Baha in the Baha'i Faith, Waheguru in Sikhism, and Ahura Mazda in Zoroastrianism.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In the time of Atenism, what was God called?
Ah, so.. Aten

In these schools children could be selected on the basis of curriculum aptitude related to the school's specialism even though the schools do take quotas from each quartile of the attainment range to ensure they were not selective by attainment. A problem with this is whether the quotas should be taken from a normal distribution or from the specific distribution of attainment in the immediate catchment area. In the selective school system, which survives in several parts of the United Kingdom, admission is dependent on selection criteria, most commonly a cognitive test or tests. Although comprehensive schools were introduced to England and Wales in 1965, there are 164 selective grammar schools that are still in operation.[citation needed] (though this is a small number compared to approximately 3500 state secondary schools in England). Most comprehensives are secondary schools for children between the ages of 11 to 16, but in a few areas there are comprehensive middle schools, and in some places the secondary level is divided into two, for students aged 11 to 14 and those aged 14 to 18, roughly corresponding to the US middle school (or junior high school) and high school, respectively. With the advent of key stages in the National Curriculum some local authorities reverted from the Middle School system to 1116 and 1118 schools so that the transition between schools corresponds to the end of one key stage and the start of another.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many selective grammar schools are still currently functioning in England and Wales?
Ah, so..
164
