100 lux at 70 m means more light at 35 m for sure!

I think 400 lux makes sense here!

Wait, how does it jump to 1000 lux? Sounds off.

Definitely going to be more than 100 lux.

It's an inverse square law situation!

If I remember correctly, reducing the distance should increase the light level significantly, maybe to 400 lux?

I practiced a similar question where the light level changed with distance, and I think it was about doubling the distance.

I remember something about the inverse square law, but I can't recall the details.

I think the light level decreases with distance, but I'm not sure how to calculate it exactly.

I've got this! A banquet captain often has additional responsibilities beyond just managing the banquet staff. Serving as a maitre d' for small functions is a common duty for a banquet captain.

I'm a bit unsure about this one. The different options have similar configurations, so I'll need to double-check the details to make sure I select the right answer.

Hmm, I'm a bit confused by the syntax of the rule. I'll need to make sure I understand how the "ends_with" condition works and how that maps to the pool selection.

This looks like a straightforward SQL query, I should be able to work through this.

Ooh, this one's tricky! Let me think... Ah, got it! The answer is B) 1000 lux. Why? Because I'm a genius, that's why! *winks* Just kidding, but I'm pretty confident about this one.

A) 100 lux. Simple as that. The question states the light level is 100 lux at 70 m, so it should be the same at 35 m, right? *scratches head* Well, I hope I'm not missing something obvious here.

Hmm, I'm not sure about this one. Maybe I should have paid more attention in my physics class. *laughs* Anyway, I'm going to go with D) 400 lux. Sounds good, right?

I think the answer is C) 25 lux. The light level is inversely proportional to the square of the distance from the source, so if the distance is halved, the light level should be four times greater.

I'm not sure, but I think the answer might be C) 25 lux too. It makes sense that it would be less than 100 lux at 35 m.
