This is all I can remember for now.

Ehem, excuse me. At this point I would like to RANT:

As you have seen, the questions were really not difficult, but you can also understand that if you didn’t read the right areas, nothing for you.
I was there cramming environmental disasters (with dates)- major oil spills (Gulf War, Exxon Valdez, Amodo Cadiz, Piper Alpha… with dates); anthropogenic disasters (all them Bhopal, Baia Mare, Chernobyl, Love Canal, Bangladesh arsenic poisoning, cyanide from gold refining, Nagasaki, Niger Delta… with dates);

Then of course: Environmental Impact Analyses, EERs, EIS, ISO 14001 to 14060 (with the names o- Environmental management Systems, Environmental Labelling, Audit, etc); Solid Waste Management (all them activated sludge, primary treatment, and gbogbo ye); osmosis, reverse osmosis, ultrafiltration, nanofiltration(with the permissible diameter sizes o);

air pollution control, water pollution and control (and fellow Evt. Eng’g people can attest to the length and boringness of those chapters, smh). Oh of course, first to fourth ‘generation’ biofuels (ie. from hemp-based biofuel of 1896 to biochar of today); hydrogen fuel cells, magnesium solar cells… this girl read oh, but what does she have to show for it??

Not to mention all those boring current affairs things. Wetin consain me with Lithuania’s RMBK nuclear reactor shut down, and their fear of being taken advantage of by Baba Russia? Or about them Ahmedjinnad, Karzai, Kim Jong Il and co? Taiwan’s healthcare system, anyone? Or Somalia horn of Africa? Opec nations (with dates they joined), Warmest years in this century due to global warming (1998 was the warmest, FYI), etc etc ETC. Yeah it pays to know stuff sha, but still, Ptdf you no try for me lol.

Ladies and Genn’lmen, it seems I am trying to show off all I know but eh, no. That is not the case at all. I just want to pen down the stuff I read (that didn’t come out) to reduce my frustration cuz I feel I wasted all that time reading and reading, only to be asked about the pH of saline soil and so forth. Hiss. If only it was theory-based and not objective; trust me, I would have added all this jara I read, wallahi! As long as there’s a tiny hint of a relationship btw. them. It’s all good sha. I have ranted.

Baibai for now. Next time I’ll include some of the past questions from previous non-objective years.
