Adverbial clauses....usage difference

[snv85]

Q1. How does an adverbial clause/phrase modify the subject or the verb of the previous clause...

Q2. i.e.What does it mean...pls illustrate why does it become ILLOGICAL...meaningwise... here in the following example...

Example 1: Part of the proposed increase in state education spending is due to higher enrollment, with a number of students in public schools growing steadily since the mid-1980’s and, at nearly 47 million, reaching.a record high.

Example 2: Emily Dickinson's letters to Susan Huntington Dickinson were written over a period beginning a few years before Susan's marriage to Emily's brother and ending shortly before Emily's death in 1886, outnumbering her letters to anyone else

Example 3: Five fledgling sea eagles left their nests in western Scotland this summer, bringing to 34 the number of wild birds successfully raised since transplants from Norway began in 1975.

here - reaching a record high,
outnumbering her letters to anyone else, and bringing to 34 the number of wild birds successfully raised since transplants from Norway began in 1975.
modify not the subject or object of preceding clause but the whole clause!

for example,
prises went up, prompting for economy recession

here , prompting for economy recession, modifies entire preceding clause- "prises went up" , not just the subject or the verb!
