Obviously Statement 1 alone is not sufficient because S1 tells us that n is a prime number
Statement 2 alone is also not sufficient because there are many numbers in that range
S1 and S2 combined
When I was solving this during the mock,I was lenient and didnt think much, I just thought there would be more than one prime between that range and hence marked the answer as E
Later I checked on the internet for the list of prime numbers and realized that there is only one prime number between 5,743 and 5,779 which is 5749.
I also noticed that both 5743 and 5779 are primes

Kindly help with this problem
How to be sure of the prime numbers between a range?
I know how to check if a number is prime (consider the nearest squre and find its square root and check for divisibility of the number by all the numbers lesser than the square root)
Is there another way?

This is a calculation intensive question - certainly not GMAT like. Ignore.
