premise: Clonaid, which claims to have produced 13 cloned babies worldwide, told the Streats daily newspaper two Singaporean couples had signed deals agreeing to pay $200,000 to conceive children through cloning.
hypothesis: Clonaid claims to have produced less than (5*5) cloned babies worldwide.
reason: They claimed to have produced 13 babies, which is definitely less than 25. It's difficult because the system does not understand that 5*5 = 25, and instead thinks it means just 5.
