1. He doesn't want newspaper men to come to the Valley of the Kings bringing lots of visitors.

2. He doesn't want newspaper men to come to the Valley of the Kings while/as they bring lots of visitors.

(Does #1 mean #2? Are both the same in meaning?)

If you use 'because' in sentence 2, the two sentences will mean about the same thing.

I respectfully disagree with the previous comment. I don't think you're looking to make both sentences mean the same but rather analyze the differences.

Although I don't know what your teacher was aiming for in giving you this question, I can tell you from my experience there are only 2 perspectives to address to your question: (a)grammatical construction, and (b)logic. Pay attention because this is a skill you will need for the SAT.

In examining both sentences for logic I find that the only word differences between the 2 are: #1-bringing; #2-While as they. The "While as" phrase can be a bit tricky so whenever I'm comfronted with a phrase that stops me I use one of its definitions to help make things easier for me.

"While as" comes from the middle-english phrase Whilst, which eventually evolved into modern english: While as meaning=> as long as they

Now lets look at #2 again using the more modern version: "He doesn't want newspaper men to come to the Valley of the Kings as long as they bring lots of visitors." Just in examining for logic we now see that the sentenses are not the same because in the 2nd sentence we learn that "HE" doesnt' want newspapermen to come in those instances when they bring visitors.

If we look at the sentences from a grammatical perspective: #1 is a complete sentence. #2 however has 2 sentences joined by "while as" which is a subordinating conjunction.

This is as far as I'm taking you because going any further would mean that I would be giving the answer. Good luck!

so

Both sentences express a similar idea but there is a slight difference in emphasis.

In #1, "bringing" is used as a gerund and functions as a noun. It suggests that the visitors are a consequence or outcome of the newspaper men coming to the Valley of the Kings. The focus is more on the visitors that will result from the newspaper men's arrival.

In #2, "while/as" introduces a clause that describes an ongoing action happening at the same time as the main action. It suggests that the visitors are present during the newspaper men's arrival. The focus is more on the simultaneous presence of the visitors and the newspaper men.

So, while both sentences convey a similar meaning, the emphasis and nuance differ slightly.
