Sketch one circle to represent Senators.
Sketch another circle, which partially overlaps the first, to represent Conservationists.
The overlapping+area shows that some+senators are conservationists.
Since the second statement means that all+conservationists+are+not+pro-development, then it follows that some+senators+are+not+pro-development.
So, the syllogism is valid.
