• The contemporary astronomer needs a telescope equipped with digital sensors to explore the universe.

Answer 1

সঠিক উত্তর হচ্ছে: The contemporary astronomer needs a telescope equipped with digital sensors to explore the universe.

ব্যাখ্যা: Modern telescopes are highly automated pieces of machinery equipped with digital sensors that produce reams of observational data. Such data can be stored, processed and distributed just like other digital information. This means it is no longer necessary for an astronomer actually to visit a telescope to make observation. So option ''d'' is correct as per the passage.
