Explanation
(1) When 'pair of' is placed before a noun, 'pair' becomes the subject and takes a singular verb. 'A pair of sunglasses is' is correct. (2) When subjects are joined by 'or,' the verb should match the subject closer to it. 'Tourists' is plural and closer to the verb, so 'have' is correct. (3) 'Information' is an uncountable noun that takes a singular verb. 'The information is' is correct. (4) When subjects are joined by 'nor,' the verb matches the subject closer to it. 'Pilot' is singular and closer to the verb, so 'was' is correct. (5) 'News' is an uncountable noun that takes a singular verb. 'The news makes' is correct. (6) When 'pair of' is placed before a noun, 'pair' becomes the subject and takes a singular verb. 'A pair of binoculars is' is correct. (7) 'Hill stations' is a plural subject, so it takes the plural verb 'remain.' (8) A gerund phrase ('Keeping accounts') acts as a singular subject and takes a singular verb. 'Keeping accounts is' is correct. (9) When subjects are joined by 'or,' the verb matches the subject closer to it. 'Bus passes' is plural and closer to the verb, so 'need' is correct. (10) When subjects are joined by 'nor,' the verb matches the subject closer to it. 'Taxi driver' is singular and closer to the verb, so 'was' is correct.
