Guys,
why is first sentence prefered over second ? I think preventing is parallel to improving rather than improved. But book says second one is correct... Please help me out??

Emotion: big smile tks for that .. but I am still confused.

First sentence
preventing illness

> adj
improving performance > adj
so first one looks alright

Second sentence
preventing illness ==> adj
improved performance ==> adj
this also looks alright..

So why do you think first one is better than second?

Hi,

tks for that .. but I am still confused.

First sentence
preventing illness
> adj
improving performance
> adj
so first one looks alright
These are not adjectives. The words are used as gerunds.

Second sentence
preventing illness ==> adj This is is not an adjective. It is a gerund.

improved performance ==> adj
this also looks alright..

So why do you think first one is better than second?

The two gerunds make a more 'parallel' sentence.

Clive....Every time I look into above sentence ,it gets over my head..ETS says sentence below is correct

Each year companies in United States could save as much as $58 billion by preventing illness among employees and gain as much as $200 billion through improved performance of workers if they simply provided offices with cleaner air.

1. How do you know improving ,preventing are not used as participle but as gerund?

2. If they are used as gerund Should we not have THE preceding improving and preventing?

3. What difference does it make...whether its being used as gerund or participle..In fact improving and preventing has no other role other than to act as an adjective to modify ILLNESS AND PERFORMANCE?

Please forgive me for my ignorance.....

Thank you
Hi,

Clive..Every time I look into above sentence ,it gets over my head..ETS says sentence below is correct I didn't tell you it was incorrect. I said that your more parallel version was better.

Each year companies in United States could save as much as $58 billion by preventing illness among employees and gain as much as $200 billion through improved performance of workers if they simply provided offices with cleaner air.

1. How do you know improving ,preventing are not used as participle but as gerund?

There is no such thing as a 'preventing illness'. 'Preventing' used as an adjective clearly makes no sense here.

One way to test whether something is a gerund is to see if it can be replaced by a noun. That is the case here. You could say

eg . . . could save as much as $58 billion by prevention of illness . . .

eg . . . could save as much as $58 billion by a program of health care . . .

2. If they are used as gerund Should we not have THE preceding improving and preventing?

No. A gerund does not always require an article. eg Tom likes dancing.

3. What difference does it make...whether its being used as gerund or participle..In fact improving and preventing has no other role other than to act as an adjective to modify ILLNESS AND PERFORMANCE? As I said above, what's a 'preventing illness'? The phrase makes no sense if you consider 'preventing' as an adjective describing 'illness'.

Clive... thanks for awesome insight.......

If I were to change the sentence...will all the option below be equally parallel and not change the meaning....

1. prevented employee illness ...... through worker performance improved ...

2. employee illness prevention ...... through worker performance improved...

3. in employee illness prevention ...... through improving performance of workers ..

4.by preventing illness among employees ..... through improved worker performance ....

Thank you
Hi,

If I were to change the sentence..(which is the above, or something close) .will all the option below be equally parallel and not change the meaning..

1. prevented employee illness .. through worker performance improved ... ungrammatical

2. employee illness prevention .. through worker performance improved... No. Employee illness prevention sounds like the employees do the preventing. That's a change in meaning.

3. in employee illness prevention .. through improving performance of workers .. Same comment as #2

4.by preventing illness among employees .. through improved worker performance .. 'Preventing' and 'improved' are not parallel words.
