I sturggled with the first one. I got four of the five correct – B_CDA, but question 2 I can’t see what can possibly make you choose between C and D.

Could you possibly explain how a D makes a contradiction there? I’m just not seeing it.

Thanks 🙂

    I also got D. It seems like C and D both work as a solution to number 2! blarghwrgjsoijghwjrh!!!

I also think C and D both works for question NO.2

In test 2, question 9 has three correct answers, because the answer is 5, which is a multiple of 5 and an odd and prime number, so I excluded 5 from the potential answers and couldn’t solve the test! I excluded any possible answer from 1 to 10 that would make question 9 have more than one correct answer. I excluded 1 (odd, prime and square), 2 (even, prime), 3 (odd, prime), 4 (even, square), 5 (odd, prime, multiple of 5), 7 (odd and prime), 9 (odd and square) and 10 (even and a multiple of 5). Where’s the mistake?
