how is the new hayden planetarium different from the old planetarium? it has a zeiss projector. it is in new york city. more stars are visible. the building’s roof is curved.
Answer
Brief Explanations:
The key is to identify a feature unique to the new Hayden Planetarium compared to the old one. Having a Zeiss - projector is likely a new and distinct feature. Being in New York City is a location fact not unique to the new one. More stars being visible could be due to multiple factors and not necessarily a defining difference. A curved roof is a general architectural feature not exclusive to the new one.
Answer:
It has a Zeiss projector.
