Wayne williams was a suspect in the murder of a number of african-american young men and boys, but was only convicted in two cases. his conviction was based on fiber samples found on victim's bodies that matched carpet in william's home and hair samples that were consistent with william's hair. many years later, dna testing confirmed that the hair matched wayne william's hair with 98% accuracy. why wasn't the dna testing completely conclusive?
a)an insufficient number of hairs were found
b) william's had a twin who lived in the area
eliminate
c) the root of the hair follicle wasn't attached
d) william's hair was identical to the victim's hair

the answer is:

in a biology class, the teacher started explaining a new lesson about the dna structure. personally, i found this lecture hard to understand. so i decided to use my critical thinking skills to be able to understand it. i analysed the different ideas, and broke them down into smaller parts to assimilate each. then i started evaluation and tried to link what i am learning with real life experiences so that i can make sure that i know how everything i am learning relates. finally, i started questioning by researching more what i learned and asking more questions that can me through my learning process. reflecting on the information meant that i should review it. all this me greatly understand what i previously found hard to understand.

hope it !
