Hello I did not know that I cannot ask question after I paid all.
I was asking that “Did you removed the yellow highlight part that i need to citation? and what is that mean about xx in page 3 (Zhang and El-Mashhad xx)” and while I was waiting, i paid all, then I cannot chat with you.
And I also wonder that you gave me the reference from here
https://www.government-fleet.com/156621/what-you-need-to-know-about-renewable-diesel

but I cannot find the page. hope you send me the link that he read.

thank you.
