Statements 1 and 2 have the pronoun 'they', which is likely to refer to a noun. That noun is 'business elite' in statement 3. Thus statement 3 would come before statement 1 and 2 . Statement 3 opens the paragraph by comparing a dieter with the business elite. The idea of social-impact-investing and philanthro-capitalism in statement 3 connects with 'they would fund million of the buzzwordy programs...' in statement 2 . Thus 32 form a pair. 4 and 1 form a pair because in statement 4 'doing the right thing would demand real sacrifice' and 'they would rather do virtuous side project assiduously'. The ideas connect. Thus 3241 form a coherent paragraph.
