instruction:
Compose a new way to ask the same question. The new question must be asking the exact same thing as the original question does. Without any other information, you should be able to tell that the original question and the new question are the same. Preserve bracketed phrases in your new question. You can change the rest of the question provided the above requirements are satisfied. The new question must have a natural, fluent formulation, as if it were composed by a native English speaker. You will be given three pieces of information to help you create better questions. Those are: "Answer": the answer to the question, e.g., "Honolulu". "Answer Type": the type of the answer, e.g., "Location". "Auxiliary Information" is a detailed description of some concepts mentioned in the question, if any.
question:
original question: Which chemical series is the element with greatest van der waals radius in along with [Oxygen]?
answer: period 2 element
answer type: Chemical Series.
auxiliary information: Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element and oxidizing agent that readily forms compounds with most elements. Photosynthesis releases oxygen, and respiration consumes oxygen. Changes in phosphate are related to changes in oxygen concentrations. Oxygen was discovered independently by Carl Wilhelm Scheele, in Uppsala, in 1773 or earlier, and Joseph Priestley in Wiltshire, in 1774, but Priestley is often given priority because his work was published first. The name oxygen was coined in 1777 by Antoine Lavoisier, whose experiments with oxygen helped to discredit the then-popular phlogiston theory of combustion and corrosion. Its name derives from the Greek roots oxys, "acid", literally "sharp", referring to the sour taste of acids and - -genes, "producer", literally "begetter", because at the time of naming, it was mistakenly thought that all acids required oxygen in their composition.
answer:
Which atomic number element in the chemical series that includes [Oxygen] has the great greatest van der waals radius?

question:
original question: how many Rocket is launched in [Guiana Space Centre]?
answer: 5
answer type: Rocket.
auxiliary information: The Guiana Space Centre or, more commonly, Centre spatial guyanais is a French and European spaceport near Kourou in French Guiana. Operational since 1968, it is particularly suitable as a location for a spaceport as it fulfills the two major geographical requirements of such a site: it is quite close to the equator, so that the spinning earth can impart some extra velocity to the rockets for free when launched eastward, and it has uninhabited territory to the east, so that lower stages of rockets and debris from launch failures cannot fall on human habitations. The European Space Agency, the French space agency CNES, and the commercial Arianespace company conduct launches from Kourou. This was the spaceport used by the ESA to send supplies to the International Space Station using the Automated Transfer Vehicle. The location was selected in 1964 to become the spaceport of France. In 1975, France offered to share Kourou with ESA. Commercial launches are bought also by non-European companies. ESA pays two thirds of the spaceport's annual budget and has also financed the upgrades made during the development of the Ariane launchers.
answer:
[Guiana Space Centre] has been launch site for how many rockets?

question:
original question: What does [Headmaster] have?
answer: marvolo gaunt's ring, elder wand
answer type: Fictional Object.
auxiliary information: A head teacher is the most senior teacher, leader and manager of a school.
answer:
