• A. a critique of all chemistry since Robert Boyle as well as a vision of a
• B. a critique of all chemistry following Robert Boyle and also his envisioning of a
• C. a critique of all chemistry after Robert Boyle and envisioning as well
• D. critiquing all chemistry from Robert Boyle forward and also a vision of
• E. critiquing all the chemistry done since Robert Boyle as well as his own envisioning of

Answer 1

Answer: (A)

a critique of all chemistry since Robert Boyle as well as a vision of a

Here, the critique and the vision that Davy's book was about need to be parallel to each other. Options B and C are not parallel as they have a noun 'critique' and then a verb 'envisioning' (in place of a noun). D is also not parallel as it has a verb 'critiquing' and a noun 'vision'. E, however, has an inappropriate way of stating things - 'as well as his own envisioning of'. Also, the use of 'his own' doesn't make sense when he is supposed to be the founder of this 'new chemistry.'Thus, A is the correct choice with parallelism and correct grammar.
