Paragraphs 8(a), (b) and (c) describe the mandate. However, Professor Leman-Langlois has just told us that the mandate is already very broad. Paragraph 8(b) doesn't restrict the mandate. Instead, it broadens the mandate, given that it includes the departments' activities. Paragraph 8(c) also broadens the mandate.
