Some of the tenth-century stave churches of Norway are still standing, demonstrating that with sound design and maintenance, wooden buildings can last indefinitely

Ron,
I have a question regarding the " ing modifier" . below is an example I am citing to understand the concept.

The ing word "Demonstrating" is acting here as an modifier that modifies the previous clause. But per the rule of "ing modifier" as you have mentioned in previous blogs that the "ing" modifier should also present the immediate results or give further information.

But in the above sentence I can't find the none these conditions being fulfilled. I know it's just I can visualize but if you will further explain the " role of word demonstrating" then I can better understand.

How is the "ing modifier" wrong here in this sentence : ( Gmat Prep Quesiton). This option is wrong. But to understand the "ing modifier" I cited this exp...
Neuroscientists have amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, are now drawing solid conclusions about how the human brain grows and how babies acquire language.

my thought was that because Neuroscientists have amassed the knowledge, resulting that they can now draw solid conclusions. Also the noun goes will along with "ing" modifier. I fail to understand where am I wrong.

thanks

the buildings are still standing --
this fact (the fact that they are still standing) demonstrates that such buildings can last for a very long time.

this one doesn't contain any _ing modifiers. ("are drawing" is a verb.)

sorry...I mistyped the one of the options : ( remove are : verb) it is then be wrong.

Neuroscientists have amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, now drawing solid conclusions about how the human brain grows and how babies acquire language.

"Drawing " is wrong here. this is what I want to understand. Doesn't it meet the rule that it is further showing what Scientists are doing with knowledge and noun also goes with this ing modifier. What in wrong with my thought process. This is what I want to understand.

Thanks

Thanks RON!!!

correct my understanding from the referred post by you : I can't use "ing" modifier, if the main clause action is in different time phase.
For ing to work as modifier, time phase for main action and ing modifier should be in same period.

Correct me if I am wrong.

[RonPurewal]

that is correct.
