The report urges convening a White House conference,

The report urges convening a white house conference. : This much is enough to make this part a complete sentence.
Rest of the sentence constitutes what the conference will do. i.e. modifying the conference and best usage will be using two parallel participle phrases.

"encouraging Congress to appropriate more money for schools" + "and" (conjunction) + "establishing networks of black mentors"

You already have definite noun(The report) to act as a subject, why do you want to use a gerund ??

IMO A

The report urges convening a White House conference, encouraging Congress to appropriate more money for schools and establishing networks of black mentors

List
<to convene> a White House conference
<to encourage> Congress to appropriate ....
<to establish> networks of..

The verbs have to be parallel

B. convening a White House conference, to encourage Congress to appropriate more money for schools and for establishing networks of black mentors >> not parallel
C. convening a White House conference, encouraging Congress to appropriate more money for schools and to establish networks of black mentors >> not parallel
D. the convening a White House conference, encouraging Congress to appropriate more money for schools and establishing networks of black mentors

Only A and E are parallel:

A. convening a White House conference, encouraging Congress to appropriate more money for schools and establishing networks of black mentors
E. for convening a White House conference, for encouraging Congress to appropriate more money for schools and establishing networks of black mentors


I will go with A, since per my info, urge does not need for.

urge someone to do something == to try to get someone to do something.
Ex. I urge you to give skiing a try.

what is the problem with C
C. convening a White House conference, encouraging Congress to appropriate more money for schools and to establish networks of black mentors

can`t we consider the second part(after the comma)as a modifier showing cause effect relationship as in
the report urges convening a ..., encouraging(effect) congress "to appropriate" ..and "to establish".

please help
thanks

Can someone please explain why C is wrong? Why cant we read it as "the report urges convening a ..., encouraging(effect) congress "to appropriate" ..and "to establish"" as pointed out by Shreygupta?

Option A (Correct): what does the report urge -> convening a conference + encouraging congress to appropriate more money + establishing networks of black mentors. Three phrases are used correctly here with AND to tell what the report says.

Option C (Wrong) : convening a conference + encouraging Congress to appropriate more money + “to” establish network of black mentors. Missing "AND continuous verb” before last phrase and hence the sentence is not consistent.

A is correct because there is no error in it ; convening , encouraging and establishing are clearly || ;

C on the other hand is grammatically correct i believe as

Encouraging modifies report and phrase " Congress to appropriate more money for schools and to establish networks of black mentors " seems to be parallel

Can C be correct here
??

Had that been the case, it should have "and" between 'convening' and 'encouraging', but not a comma.

Can someone point out the error I made here:
The report urges convening a white house conference,
- encouraging congress
- to appropriate more money for schools and
- to establish networks for black mentors.

This is the parallelism chart I understood and hence chose C. Why is this incorrect ?

You have one gerund and 2 infinitives, so they're not parallel.

isnt oxford comma missing in option A
convening, encouraging, and establishing

Posted from my mobile device

Oxford comma is not required in a list.

First thing first,
I have some basic foundational problems on some issues of grammar.
Can anyone help me to understand the basics of how "convening a White House conference" could act as an object in this sentence?
My inner sense said that, "-ing" thing either should be (a modifier) or (be verb + ing).
but here I found, it works like an object.

please give me an assist.

The report urges convening a White House conference,
encouraging Congress to appropriate more money for schools and
establishing networks of black mentors

Doing the Meaning Analysis of the above sentence the report urges 3 things: convening ...,encouraging...,and establishing
But would it be more appropriate to say that the action 'convening'(call for a meeting) with the intention to encourage.. and establish...
As per above analysis (B) should be the correct option??
