Problem: Insect:

Insects (from Latin insectum, a calque of Greek [entomon], "cut into sections") are a class of invertebrates within the arthropod phylum that have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. They are the most diverse group of animals on the planet, including more than a million described species and representing more than half of all known living organisms. The number of extant species is estimated at between six and ten million, and potentially represent over 90% of the differing animal life forms on Earth. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, a habitat dominated by another arthropod group, crustaceans.

In what phylum are insects classified?

A: arthropod

Problem: The above explanation is merely a simple introduction to vacuum pumping, and is not representative of the entire range of pumps in use. Many variations of the positive displacement pump have been developed, and many other pump designs rely on fundamentally different principles. Momentum transfer pumps, which bear some similarities to dynamic pumps used at higher pressures, can achieve much higher quality vacuums than positive displacement pumps. Entrapment pumps can capture gases in a solid or absorbed state, often with no moving parts, no seals and no vibration. None of these pumps are universal; each type has important performance limitations. They all share a difficulty in pumping low molecular weight gases, especially hydrogen, helium, and neon.
What can positive displacement pumps achieve more than entrapment pumps?

Context and question: Haredi Judaism advocates segregation from non-Jewish culture, although not from non-Jewish society entirely. It is characterised by its focus on community-wide Torah study. Haredi Orthodoxy's differences with Modern Orthodoxy usually lie in interpretation of the nature of traditional halakhic concepts and in acceptable application of these concepts. Thus, engaging in the commercial world is a legitimate means to achieving a livelihood, but individuals should participate in modern society as little as possible. The same outlook is applied with regard to obtaining degrees necessary to enter one's intended profession: where tolerated in the Haredi society, attending secular institutions of higher education is viewed as a necessary but inferior activity. Academic interest is instead to be directed toward the religious education found in the yeshiva. Both boys and girls attend school and may proceed to higher Torah study, starting anywhere between the ages of 13 and 18. A significant proportion of students, especially boys, remain in yeshiva until marriage (which is often arranged through facilitated dating see shiduch), and many study in a kollel (Torah study institute for married men) for many years after marriage. Most Orthodox men (including many Modern Orthodox), even those not in Kollel, will study Torah daily.
Who is not allowed to proceed to higher Torah studies?
Answer: unanswerable

Question: Downstream operations, which now also includes the chemicals business, generates a third of Shell's profits worldwide and is known for its global network of more than 40,000 petrol stations and its 47 oil refineries. The downstream business, which in some countries also included oil refining, generally included a retail petrol station network, lubricants manufacture and marketing, industrial fuel and lubricants sales and a host of other product/market sectors such as LPG and bitumen. The practice in Shell was that these businesses were essentially local and that they were best managed by local "operating companies" often with middle and senior management reinforced by expatriates. In the 1990s, this paradigm began to change, and the independence of operating companies around the world was gradually reduced. Today, virtually all of Shell's operations in various businesses are much more directly managed from London and The Hague. The autonomy of "operating companies" has been largely removed, as more "global businesses" have been created.
Is there an answer to this question: How many oil refineries does Shell have?

Answer: unanswerable

The Premier League distributes a portion of its television revenue to clubs that are relegated from the league in the form of "parachute payments". Starting with the 201314 season, these payments are in excess of 60 million over four seasons. Though designed to help teams adjust to the loss of television revenues (the average Premier League team receives 55 million while the average Football League Championship club receives 2 million), critics maintain that the payments actually widen the gap between teams that have reached the Premier League and those that have not, leading to the common occurrence of teams "bouncing back" soon after their relegation. For some clubs who have failed to win immediate promotion back to the Premier League, financial problems, including in some cases administration or even liquidation have followed. Further relegations down the footballing ladder have ensued for several clubs unable to cope with the gap.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): To which type of team are parachute payments distributed to in the Premier League?
Ah, so..
relegated
