B seems best: the blast furnaces for smelting pig iron with coke

reasoning: the list seems most PARALLEL with option B :the spinning jenny, the power loom,the blast furnaces for smelting pig iron with coke , and the steam engine played a key role.

I fully endorse Pictureperfect and aditya; The innovations included four types of machinery that increased productivity, namely a spinning jenny that could increase yarn production hundred times more, a power loom that produced thousands of yards of fabric compared to the paltry quantity by the hand weaving, a blast furnace that smelt thousands of tons of ore to produce metal and finally a steam engine that propelled huge engines such as trains and ships.

I am particularly critical of the choice C, which mixes up a process in the midst of other machinery in the name of noun parallelism, which is indeed an ante-parallelism in an otherwise cohesive group. After all, the true parallelism is when you describe each of them as an adjective followed by a noun: spinning jenny, power loom, blast furnace and steam engine

there can be no doubt that technological innovations such as - [ Providing Examples ]

1. the spinning jenny,
2. the power loom,
3. smelting pig iron with coke in blast furnaces, and
4. the steam engine played a key role


To maintain parallelism The is necessary in the 2nd Example

Among B , C and D only (B) fits in perfectly...

This is kind of a trick question. Yes, a blast furnace is an object and "the smelting" is not, but that's the point. The sentence is listing innovations. The sentence makes it clear that the smelting, not the blast furnace, is the innovation. Every single choice mentions smelting, not just the furnace itself. Notice that all of the other choices mention the device only. There's a reason this one is different!

Would the real GMAT pull this trick? Perhaps. You certainly wouldn't be expected to know that the blast furnace is actually a much earlier invention than the other four, but you might be expected to work for parallelism of concept rather than simple parallelism between similar nouns. The GMAT requires flexibility and attention to meaning!

As far as I know, smelting was prevalent from pre-historic times. Remember the Bronze Age and the Iron Age, when tools and other utilities that were made after smelting the ores?. So smelting was no innovation. It was smelting in blast furnaces that was the innovation, with the furnace itself having been created as recently as in early 19th century

I think, if the topic wanted to say about innovative machines or innovative processing, then the good old ordinary smelting has no chance to be included in that list. It is the blast furnace, invented a little before the Industrial revolution, that was responsible for great strides in metallurgy.

In terms of chronology, the spinning jenny, the steam engine and the power loom were all 18th century creations while the blast furnace belonged to the late 18th and early 19th century. In comparison, the industrial revolution occurred in the late 19th century and early 20th century. This info, I hope, can help us to fix what the causes of the industrial revolution’s great positive impact were.

So I feel smelting in C has no locus standi.

So, of course one shouldn't have to know any of this history to do an SC problem, but neither blast furnaces nor smelting is a recent innovation. The innovation is the whole thing: the smelting of pig iron with coke in blast furnaces. We don't need history for this--it's simply the only way the sentence makes any sense. However, if you want the history, it's here: http://www.bbc.co.uk/history/british/vi ... nace.shtml

Hi, I was wondering could one of you experts please explain the difference between option B and D? I was able to get down to B and D but ended up picking option B instead mainly because I assumed that the "blast furnaces" was one of the innovations instead of "the smelting of pig iron". Furthermore, I thought B was rather more concise than D. Please help! Would immensely appreciate it!

I hate to say this, but I wouldn't worry about this question at all. You've heard the disclaimer before: the GMAT spends between $1500 and $3000 developing each official question, and even the very best test-prep companies just can't compete with that.

In this particular case, I actually agree with you: the other three items in the parallel list are all common nouns, not gerunds, and it makes perfect sense to me that the "blast furnaces" themselves are the innovation.

So please don't waste your time worrying about this particular question. Instead, check out this official question that has a vaguely similar parallelism issue: https://gmatclub.com/forum/qotd-geologi ... 52482.html.
