A diagram is a way of tracking your information all together and a illustration is a picture of anything like a picture in a book
1st one is the 1st one bc a simile is using “like or as” saying that he/she feels like a bird
2nd one is the 3rd one bc he/she is tired of ppl staring at him/her
3rd one is I think the 3rd one not 100 % tho
4th one is the last one if the 3rd one is right
5th one is the 2nd one (I think)
Sorry if I got them wrong they are a bit hard
I would go with although both elephants,Asian and African elephants ate different in size ,genetics and habitat
