Elliott, a 43-year-old engineer, has volunteered to teach a group of middle-school students some hands-on engineering basics, hoping to get them oriented toward a math-science career path. Performance of the 1/3 of the group, who are girls, is lower than average. What is one likely cause for this effect?

i think its toxic gasses but i could be wrong

explanation:

allergens: overstimulate the nerve system

neurotics: attack nerve cells

mutagens: damage or otherwise alter dna sequence

generators: cause defects during growth and development  

carcinogens: cause unchecked cell growth

i hope you get the idea according to me these are the effects that happened.

i feel as if they would both catch on before to long because they would see them to frequent
