Does anyone have an answer key for "Pick and Choose Multiple Choice Comprehension Passages - Robert Best?

Hi

Does anyone please have an answer key for "Pick and Choose Multiple Choice Comprehension Passages - Robert Best?

It is an 1971 publication (ISBN 0582523176), but I cannot find a copy with answers or a seprate answer booklet. I have tried Amazon.

For context it was for students studying English at an intermediate level. The standard of passages is that of the Cambridge Lower Certificate Examination.

Thanks
