Input: Read this: The "Lophotrochozoa" hypothesis is also supported by the fact that many phyla within this group, including annelids, molluscs, nemerteans and flatworms, follow a similar pattern in the fertilized egg's development. When their cells divide after the 4-cell stage, descendants of these 4 cells form a spiral pattern. In these phyla the "fates" of the embryo's cells, in other words the roles their descendants will play in the adult animal, are the same and can be predicted from a very early stage. Hence this development pattern is often described as "spiral determinate cleavage".
Question: What phyla is no longer able to make eggs?

Output: unanswerable


Input: Read this: The black-body problem was revisited in 1905, when Rayleigh and Jeans (on the one hand) and Einstein (on the other hand) independently proved that classical electromagnetism could never account for the observed spectrum. These proofs are commonly known as the "ultraviolet catastrophe", a name coined by Paul Ehrenfest in 1911. They contributed greatly (along with Einstein's work on the photoelectric effect) to convincing physicists that Planck's postulate of quantized energy levels was more than a mere mathematical formalism. The very first Solvay Conference in 1911 was devoted to "the theory of radiation and quanta". Max Planck received the 1918 Nobel Prize in Physics "in recognition of the services he rendered to the advancement of Physics by his discovery of energy quanta".
Question: What name did Paul Ehrenfest give to the proofs from Einstein and Rayleigh & Jeans?

Output: the "ultraviolet catastrophe"


Input: Read this: The origins of al-Qaeda can be traced to the Soviet war in Afghanistan (December 1979 – February 1989). The United States, United Kingdom, Saudi Arabia, Pakistan, and the People's Republic of China supported the Islamist Afghan mujahadeen guerillas against the military forces of the Soviet Union and the Democratic Republic of Afghanistan. A small number of "Afghan Arab" volunteers joined the fight against the Soviets, including Osama bin Laden, but there is no evidence they received any external assistance. In May 1996 the group World Islamic Front for Jihad Against Jews and Crusaders (WIFJAJC), sponsored by bin Laden (and later re-formed as al-Qaeda), started forming a large base of operations in Afghanistan, where the Islamist extremist regime of the Taliban had seized power earlier in the year. In February 1998, Osama bin Laden signed a fatwā, as head of al-Qaeda, declaring war on the West and Israel, later in May of that same year al-Qaeda released a video declaring war on the U.S. and the West.
Question: What took place from February 1979 to December 1989?

Output: unanswerable


Input: Read this: Economic growth in Swaziland has lagged behind that of its neighbours. Real GDP growth since 2001 has averaged 2.8%, nearly 2 percentage points lower than growth in other Southern African Customs Union (SACU) member countries. Low agricultural productivity in the SNLs, repeated droughts, the devastating effect of HIV/AIDS and an overly large and inefficient government sector are likely contributing factors. Swaziland's public finances deteriorated in the late 1990s following sizeable surpluses a decade earlier. A combination of declining revenues and increased spending led to significant budget deficits.
Question: How much higher is the Swazi GDP growth compared to the rest of the SACU?

Output:
unanswerable
