In the middle of the 19th century, mathematician turned computer scientist Ada Lovelace aided Charles Babbage by developing the first computer algorithm, a breakthrough that ushered in the computer age, leading to machines capable of executing functions far more rapidly than could any possible human and resulting in every subsequent development in the field, from the development of the very first personal computer nearly a century later to the programs that today sequence genomes.

There is no need to consider other than the underlined part. This is essentially a test of modification

1. Mathematician turned computer scientist Ada Lovelace aided Charles Babbage by developing the first computer algorithm, a breakthrough that ushered in --- looks like the best since the appositive adequately refers to the algorithm.


2. Ada Lovelace, mathematician and computer scientist, aided Charles Babbage by developing the first computer algorithm, ushering in --- The adverbial modifier 'ushering in' is a problem, since it now modifies not the algorithm but Ada aiding Charles.

3. Ada Lovelace, who was a mathematician turned computer scientist, aided Charles Babbage in developing the first computer algorithm, which ushered in --- 'In developing' alters the meaning. It means that it was Charles who developed the algorithm, while it was Ada who actually did it.

4. the mathematician turned computer scientist, Ada Lovelace, aided Charles Babbage in developing the first computer algorithm; she ushered in … a couple of wrongs. 1. 'In developing'. 2. -She ushered in- is wrong; it was the algorithm which ushered in.

5. Ada Lovelace, the mathematician turned computer scientist, aided Charles Babbage by developing the first computer algorithm, ushering in ... The adverbial ushering in is wrong as explained in choice two.

A deep question as usual from Magoosh.

I am not sure why you would think so.
How did Ada aid Charles?.. by developing.
I do not see any problem with this construction.

1. mathematician turned computer scientist Ada Lovelace aided Charles Babbage by developing the first computer algorithm, a breakthrough that ushered in
--> correct.

2. Ada Lovelace, mathematician and computer scientist, aided Charles Babbage by developing the first computer algorithm, ushering in
--> , v-ing is wrong here.

3. Ada Lovelace, who was a mathematician turned computer scientist, aided Charles Babbage in developing the first computer algorithm, which ushered in
--> we need "essential modifier", not "non-essential modifier".

4. the mathematician turned computer scientist, Ada Lovelace, aided Charles Babbage in developing the first computer algorithm; she ushered in
--> "she" is ambiguous.

5. Ada Lovelace, the mathematician turned computer scientist, aided Charles Babbage by developing the first computer algorithm, ushering in
--> , v-ing is wrong here.
