Answer:
I believe the answer to question #1 is A- "An article in a scientific journal about the effects of gasoline emissions on the environment."
I'm not certain with question #2, but I'm pretty sure it's A- "Robots can make life easier for humans because they can research and problem solve."
Question #3 is answer B- "The small pond was teeming with tadpoles minnows."
I believe the answer to question #4 is C- "Emma's reliance on her sister's sage advice, as well as her commitment to daily practice, allowed her to be selected for the team."
Explanation: I really just took my best guess. For questions 1, 2, and 4, I'm not completely sure that those are the answers. Just tried to guess since I saw no one else answered with actual answers. For question 3, I am very very certain that is the correct answer.
Hope this helps though. :) Have a good day!
