Thank you for using the timer!

There are many benefits to timing your practice, including:
I cannot copy and paste this file so I would have to deviate from my normal style.
First A sound awkward for a number of reasons. first the use of since always connotate time and therefore it is awkward to say since Robert Boyle . At best it best since robert Boyles's time. Seecondly' a new vision that Davy hope to found introduced at the end of this sugest that Davy is criticising his own vison which is not the case
B is the right choice. It corrects the problem in A by using after for since. secondly it correctly says that Davy hope to critique the Roberts Envisioning of a new Chemistry, which makes sense.
the other choice does not present a greater challege here except E but E also cannot be right because Davy cannot critiigue his own envisoning of new Chemistry
B has many problems, first and foremost the lack of parellelism. You shouldn't combine critique with envisioning. One is an ordinary noun, while the other is a gerund.
Secondly, B uses following to indicate the lapse of time since Doyle. Davy here is not doing a followup to anything.
A is a good choice. The use of since to indicate time passed after an event is acceptable. Robert Doyle embodies an event -- a happening -- and while appending time to it would be better, the phrase just the way it is looks fine to me. (Compare with since WWII.)
