Soot is an example of: A. a primary pollutant

Primary pollutant refers to a pollutant that come up directly from the source. Soot is created when we burn organic compounds into  black substances consisting of amorphous carbon.

Without being burned, organic compounds are not considered as pollutant.  Since the creation of soot does not happen because of the chain reaction caused by other pollutant, we can consider soot as a primary pollutant.

elizabeth loftus conducted a study to observe the reliability of eyewitnesses during the 1970s. their baseline was to define how accurate are the recollections of eyewitnesses.

her studies do not support the use of eyewitness. loftus mentions in her work that we are not required to recall some experiences, meaning that rarely an individual eyewitness testimony is trustworthy. a good example is presented in her work, where all individuals watched a video and were than asked "about how fast were the cars going when they hit/smash? ". the testimonies changed based on the word she used to make the question (hit or smash), proving the fragility.

the correct answer is "hematoma formation, with ligaments that are stretched, partially, of fully torn" ankle sprain are produced by an injury to the tough bands of tissue (ligaments) that surround and connect the bones of the leg to the foot. this causes several damage to the ankle including hematoma formation and ligament injury .
