Welcome to Half-Life Answers. What would you like to know?

Because the test subjects that were supposed to solve these tests were given an ASHPD before entering the chambers.

(Also the first test has a poster next to the catwalk before entering it. It reads:

"This test is unsolvable without an Apeture Science Portable Quantum Tunneling Device.

If you have not recieved one please find a Test Associate before participating in any Shaft 09 Enrichment Activities.)
