I mean, you could probably put a short version of your title like "How Polluted Are Our Waterways", but you should have a tighter title that's not a question like "Our Polluted Waterways and the Threat They Pose".
Yeah you're marked on how focused the essay is. Also since they've already submitted the essay this is just to help it be found so it has to have the same title
In 2015, I had a part time job managing some parts of my University's IT. We still had 2 Sparc64 build servers that were like 15 years old and had a dual socket MB with 2 physical CPUs and 2 GB of RAM. Top of the line when it came out. It took like 10 seconds for ls to run. Most infra had moved to x86_64 CentOS machines (from Sun Microsystems still, so like 10 years old), but we were still routinely building updated dovecot packages for the Sparc64 machines managing internal email.
I agree. It's supposed to be the title, not an article. 🙂 Posing it as a question does help to pique interest, though. Could do... "Are polluted waterways a major threat?" Boom. Done.
