Ship safety and environmental protection, E-Pariksha questions with answers

Here we are providing you with previous asked E-pariksha questions from the paper "SHIP SAFETY AND ENVIRONMENTAL PROTECTION ". We request all users not to copy paste our content anywhere. The questions are divided into different pages for simplicity. If anyone feels that the any of the answers are wrong, we request the users to give the correct answer in the "comment column" along with the source in that page itself, if you have any. This will be helpful for others also and will be available for ever. The questions are not repeated here (like facebook). so if u give any link or proof to any answers, I will be available here at all times. We have also integrated "facebook comment" in the page to make the process easy. The feedback is also expected from the users to make necessary changes. If this is helpful for the candidates, then we are also planning to publish the same model of papers for all subjects of MEO Class4. So your feedback is valuable for us.
