Is n't this an absolute phrase (Noun + Noun Modifier), which could be used to describe an idea mentioned elsewhere in the sentence before comma.
for example:
Scientist have found high levels of iridium in certain geographical formations arouond the world, results that suggest the cataclysmic impact of a meteor millions of year ago.
If Yes, then part can modify purchase / acquisition
the difference is that "results" is an ABSTRACTION. abstract nouns are allowed to stand for the whole idea of the preceding clause, rather than just the preceding noun or noun phrase.
see here:
post35386.html#p35386"a part of a deal" is CONCRETE, so it stands for the preceding noun.
the distinction is subtle, but important.
for another example of
comma + concrete noun (again, standing only for the preceding noun) in a correct answer, see here:
yellow-jackets-number-among-the-900-or-so-species-of-the-t3105.html2) C) million, part of a deal making
What is the usage of Present partciple without a comma
(I understand that ", Present participle" would modify the previous action/clause)
For example, In choice C, Is making directly modifying deal?
if there's NO COMMA, then -ING marks the
preceding noun (in much the same way as would a clause with "that" or "which").
3) Which of the following is correct between
An asteroid bigger than Mount Everest slammed into North America, Sixty-five million years ago, an event that caused plant and animal extinctions marking the end of the geologic era known as the Cretaceous Period.
AND
An asteroid bigger than Mount Everest slammed into North America, Sixty-five million years ago, an event that caused the plant and animal extinctions that mark the end of the geologic era known as the Cretaceous Period.
Thanks in advance
they're both fine. the repetition of "that" in the second one is sort of ugly, though.
there's a slight difference in meaning.
* in the first one, "marking" is simultaneous with "caused", since that's how -ing modifiers work: they adopt the tense of the clause to which they're attached (see here:
post35042.html#p35042). therefore, the first one indicates that these events marked the end of the era
at the time when they occurred.
* in the second one, "that mark" is in the present tense, indicating that this timeline is valid from the point of view of today's observers.
both of the above meanings make sense, so both versions are technically fine.
