I will bet they will know for sure to the level that you can bet your life on the result.
If you want absolute certainty, then you are living in the wrong world.

in accidents like these, there is a lot of contributing factors, neither of which could have caused the crash by itself. However, when they are working together, there is a synergy between them which leads to disaster. Even if you had all the data, you might not be able to tell if the crash really happened because of flying into thunderstorms, or pitot tube design, or lacking AoA indication, or excessive unmanageable automation, or lack of high speed, high altitude stall training/awareness, or something else. You can pick one reason and call it THE reason, but others will disagree with you, and the argument will just go on endlessly.
