Total words: 1000. Be sure to answer in your own words. Your homework assignment will need to be submitted through canvas. Your turnitin index needs to be below 50%. Copying and pasting material will result in a grade deduction. For each percentage point your turnitin index is above 50%, your grade will be reduced by 1%. For example, if your turnitin index is 70%, that's 20% above 50%, so your grade would be reduced by 20%.
