I want to know the answer to the following question:
What did Lamb and Murdoch believe to be the best indicator of newspaper quality?
All the background I'm provided with is that "He was scathing in his opinion of the Mirror, where he had recently been employed as a senior sub-editor, and shared Murdoch's view that a paper's quality was best measured by its sales, and he regarded the Mirror as overstaffed, and primarily aimed at an ageing readership.". Is that enough to answer the question?
Answer: yes
