@sydneygrube, happy to help!We are told that the truck must be cleaned between different materials and can only be cleaned a maximum of three times. We are also told that the fifth load is mulch. Combining these pieces of information, we see that it would be impossible to arrange the seven loads without placing at least two loads of mulch consecutively. If we didn't immediately get this, we can approach the question by coming up with scenarios that prove that (A), (B), (C), and (E) could be false.
Does that make sense? Please let us know if you have any other questions!

Thank you so much! That makes sense!christina on September 11, 2020
Am I somehow misunderstanding what answer choice (D) means by "at least two loads of mulch need to be hauled consecutively"? I have the following scenarios (which Naz also got) with only one load of mulch is hauled:M | S S S | M M | S
M | S S | M M | S S
S S S | M M | S | M
M M | S S | M | S S

I am having trouble on this entire game as one of my deductions is MS|MS|MS|S. Why isn't this a valid deduction?
