How many minor languages are spoken in afghanistan? what are the positives and negatives to such linguistic and culture variance?

I will try to answer only on the first question of yours. Minor languages may include Hindi-Urdu, Punjabi, Ashkunu, Kamkata-viri, Vasi-vari, Tregami and Kalasha-ala, Pamiri (Shughni, Munji, Ishkashimi and Wakhi), Brahui, Arabic, Qizilbash, Aimaq, and Pashai and Kyrgyz. Linguist Harald Haarmann believes that Afghanistan is home to more than 40 minor languages, with around 200 different dialects.

for this case, we must find the number of deaths per day of the year 2015, in automobile accidents, knowing that 32,400 people died.

knowing that the year 2015 had 365 days we have the following division:

where "x" represents the number of deaths per day.

rounding off we have:

approximately, 89 people per day died in 2015

answer:

89 people per day
