C? Really? I didn't know the genesis block hash was in there.

I think D is also important, but A is the main one.

Definitely A! Merkle root and previous block hash are key.

I’m a bit confused; does the block header really include the timestamp? I thought that was just for the block itself.

I feel like I've seen a question similar to this before, and it was about the hash of the previous block being essential.

I remember studying that the Merkle root is important for block headers, so maybe A is correct?

I think the block header includes the hash of the previous block, but I'm not sure if that's the only thing.

Hmm, this is a tricky one. I'm thinking the fastest way would be to failback to the blue stack, since that's already known to be working. Rebooting the servers could take a while, and restoring from backups would be even slower.

I'm a little confused by this question. I know Surface Automation has different navigation actions, but I'm not sure which one is specifically used to press a button that's been identified as a Region. I'll have to re-read the question and options more closely.

This is a tricky one. I want to make sure I don't overthink it and miss something obvious. I'll read through the choices carefully before deciding.

I'm not sure about this one. The fractions and overlapping sets are throwing me off. I'll need to draw a Venn diagram to visualize it better.
