This post was
BOOKMARKED
Essentially the issue is not primarily about the use of as well as or along with.
In A the lack of main verb is the issue.
In B, the issue is about //ism between caused by and ((caused) along with; caused in the second arm is elliptical. Caused by X as well as by Y is the correct version. There is a cause and effect factor here; along with cn not bring about cause and effect so well that //ism suffers not only structurally but also logially.
In C the above two issues have been solved.
In D, the issue is S- V agreement between ‘a spurt’ and ‘have caused’.
In E, the issue is that the tense of the verb has been changed to past tense from the original present perfect and once again a S- V mismatch between heavy truck movement and were

So the issue is indeed complex and not restricted to as well as or along with, which by virtue o being prepositional phrases are nothing much different in the given context.

Ok I get it now.. I thought both X and Y contribute to the cause together, thats why the use of "along with". But the issue here is that both X and Y contribute independently to the cause..

This question got me worrying about a couple of things.
a. how to answer such questions in 90 seconds.
b. How to make splits in such lengthy sentences.

Well let me give my perception of how to handle long passages. Firstly, in most of the cases, it is no more a ploy than to intimidate the candidate. Most of them are decided by simple and basic grammar principles such as S-V number mismatch, basic tense and comparisons, fragmentations and run-ons. I have not found most of them go deep into meaning. Sometimes the wrong choices omit some part of the original passge and to tht extent alter the meaning.

However, the basic approach will be to strip the passage naked by getting rid of the unnecessary modifier phrases and reduce the bulk.

For example, let us take the case in question.

The recent spate of traffic jams on Beijing-Tibet highway reportedly caused by a spurt in traffic by heavy trucks carrying coal and heading to Beijing as part of the illegal trade in coal that has flourished due to lack of government control enroute as well as by the delayed response of the maintenance agencies to undertake timely repairs to the roads damaged in the recent incessant rains

Now in this case, if you try to match the subject of spate with its due verb, you will see that you do not have one. So now, you search a working verb. B and C are properly verbed by was caused. So keep them.

In D, the subject is the singular spurt, but the verb is ‘having caused’.

In E, the subject is movement and the verb ‘was caused’ (as well as has no role here)

Now between the B and C, B misses the ‘by’ parallelism. C is perfect.

Therefore, no need to worry about coal trade or traffic jam or the maintenance delay, those modifiers purposely stacked for distracting

Another example:

Humans have been damaging the environment for centuries by over cutting trees and farming too intensively, and though some protective measures, like the establishment of national forests and wildlife sanctuaries, having been taken decades ago, great increases in population and in the intensity of industrialization are causing a worldwide ecological crisis.
though some protective measures, like the establishment of national forests and wildlife sanctuaries, having been taken decades ago, great increases in population

though some protective measures, such as the establishment of national forests and wildlife sanctuaries, were taken decades ago, great increases in population

though some protective measures, such as establishing national forests and wildlife sanctuaries having been taken decades ago, great population increases.

with some protective measures, like establishing national forests and wildlife sanctuaries that were taken decades ago, great increases in population

with some protective measures, such as the establishment of national forests and wildlife sanctuaries, having been taken decades ago, great population increases

What is the verb for the subordinate clauses starting with ‘though some protective measures’? You will see that only choice B has a working verb and hence that is the choice.

Example 2
In attempting to solve the problems caused by a lowering of the price of oil, oil companies operating in the North Sea have taken a variety of approaches, which includes their reducing employment, using new technology to pump oil more efficiently from smaller fields, and finding innovative ways to cut the cost of building and operating platforms.

which includes their reducing employment, using new technology to pump oil more efficiently

which includes reducing employment, using new technology to be more efficient in pumping oil

which include reducing employment, using new technology to pump oil more efficiently

which include the reduction of employment, their using new technology to pump oil more efficiently

including a reduction of employment, their use of new technology to be more efficient at pumping oil

Even a cursory glance will make out that it is approaches which include, an not includes. So A and B are out; then it is simple list parallelism among C, D and E, you can see C fits the bill easily.

Take away; If you see a big passage, fall back on grammar first.

I have never seen a SC problem this long. Isn't this a bit unrealistic? Either way, I read each sentence and knocked it down to C and E. Re-read each, caught the cause/causes thing in E and went with C.

IMO C, A lacks a "was", B "along with" distorts the meaning, D,E is not structurally readable. Hence C.

1. use of due to is not correct.
2. by spurt in traffic in passive voice is not correct. (refer chapter 5, MGMAT SC) better because or through would have been used rather than by.

I got it wrong with A. Can someone explain the difference between 'along with' and 'as well as'.

Both are grammatically correct. However, when you end up in a situation where there are two options and both are grammatically correct, chose the option that is more closer/similar to the original sentence.
