The success of the program to eradicate smallpox has stimulated experts to pursue what they had not previously considered possible - better control, if not eradication, of the other infections such as measles and yaws.
1. what they had not previously considered possible - better control, if not eradication, of the other infections such as
2. what they had not previously considered possible - better control, if not eradication, of the other infections like
3. something they had not previously considered possible - better control, if not eradication, of such infections as
4. something had not considered a previous possibility- better control, and perhaps eradication, of other infections such as
5. the possibility of what they had not previously considered - better control and possibly eradication of infections like
The Splits:
Such as Vs Like:
Such as:
It is used to introduce example.
Like:
It is used to mean similarity.
-> This rule eliminates B and E.
Consider the skeleton of the sentence:
The success has stimulated experts to pursue what they had not previously considered possible - better control, if not eradication, of the other infections such as measles and yaws.
Fit the option D as follows:
The success has stimulated experts to pursue X had not considered. -Fine.
We need "X + Subject + verb".
We can write the sentence as follows.
The success has stimulated experts to pursue X they had not considered. -Fine.
Another problem with D is "the previous possibility". What does it mean? It means that "X was a previous possibility, and it has no more possibility". It is not the intended meaning of the sentence.
So, D is eliminated.
We are between A and C.
The split is between "the other infections Vs Infections":
A. what they had not previously considered possible - better control, if not eradication, of the other infections such as
In this option, we are giving examples of other infections by using such as, so it means that there could be more infections than just measles and yaws that were earlier considered not possible.
C. something they had not previously considered possible - better control, if not eradication, of such infections as..
=> This option limits the possibility to only measles and yaws.
Two students have requested me to say something about the use of "WHAT"
I have analyzed that "what"has been used correctly in OG and in GMATPREP.
I am giving a list of them.
The following examples are from GMATPEP:

Wateree, anchored in the harbor of Arica, off the coast of what is now northern Chile, rode on the crest of a tsunami (seismic sea wave) and came to rest in the Atacama Desert, some three miles up the coast and almost two miles inland from its initial anchorage.]

The following examples are from Official Guides:
1� The period when the great painted caves at Lascaux and Altamira were occupied by Upper Paleolithic people has been established by carbon-14 dating, but what is much more difficult to determine is the reason for their decoration, the use to which primitive people put the caves, and the meaning of the magnificently depicted animals.
2� Carnivorous mammals can endure what would otherwise be lethal levels of body heat because they have a heat-exchange network that keeps the brain from getting too hot.
3� Scientists have recently discovered what could be the largest and oldest living organism on Earth, a giant fungus that is an interwoven filigree of mushrooms and root like tentacles spawned by a single fertilized spore some 10,000 years ago and extending for more than 30 acres in the soil of a Michigan forest.
4� His studies of ice-polished rocks in his Alpine homeland, far outside the range of present-day glaciers, led Louis Agassiz in 1837 to propose the concept of an age in which great ice sheets existed in what are now temperate areas.
Please analyze the how "what" has been used in the these correct sentences.
Thanks.
