I agree with all the work people have done here. A quick note about singular/plural in this construction. Both of the following can be correct:
"Rising interest rates make borrowing more expensive."
"Rising interests rates makes borrowing more expensive."
The difference between the two is that in the first examples, we are talking about the various interest rates that are rising individually. In the second example, we're referring to the collective rising of interest rates.
"The attitude of students in my class is generally negative." --> Here we're referring to the collective, overall attitude.
"The attitudes of students in my class are generally negative." --> Here we're referring to the attitudes individually, and we're saying that maybe 9 out of 11 are negative.
The difference between the students and interest rates example is that you can't make "Rising" plural...at least not in English.
