Q1. Jai Singh II did not build an observatory at which of the following places?
Explanation
Sawai Jai Singh II is known for building observatories, or Jantar Mantars, at Delhi, Jaipur, Ujjain, Mathura and Varanasi. The question asks for the place where he did not build one among the given choices. Delhi, Mathura and Ujjain are all part of the recognised list of his observatory sites. Agra is not included in that list, so it is the correct response for the negative wording of the question. The wording must be read carefully because it asks for the exception.
