Answer: b)because near-critical paths could become critical paths with small delays in these activities
Explanation: Program evaluation and review technique(PERT) technique is used for management of the project .The organizing, maintenance,coordination of any task is done by this chart. The non-critical activities need to be observed carefully because they may create near-critical methods which can lead to complexity.
Other options are incorrect because not all activities are equally rather monitoring is done to avoid errors and slack can occur at any path . Small delays can be caused but not complete project can get delayed and there can be risk of complexity rather than being uncompleted.Thus, the correct option is option(b).

Answer:
megapixel refers to the unit of resolution i.e. one million
Explanation:
Interestingly the higher the pixels does not mean higher quality of image, it's more about the camera and it's sensor.
I am a photographer and a licensed drone pilot and have researched the subject to help with camera choice, both DSLR and drone.
 
        
             
        
        
        
Based on the definition which states it is an indicator of oxidation of an atom in a chemical compound. I believe the most viable answer is the charge of an atom's ion.
