MGMAT book is confusing on this topic... (MAJOR SC question)

by Stockmoose16 » Fri Aug 08, 2008 8:38 am
According to the MGMAT book, one should ignore the "of clause" when trying to determine the subject of a verb. But, it appears that rule doesn't apply to the following examples, which are from SENTENCE CORRECTION questions:

1) A new species of sparrow has/have been found.
-- Should this be plural because of 'species' or singular because of 'sparrow'

2) "The pattern of changes that have occurred in human DNA over the millennia indicate/indicates the possibility that everyone alive today might be descended from a single female ancestor who lived in Africa sometime between 140,000 and 280,000 years ago."
--Should it be indicate or indicates, since it's preceded by "the pattern" (singular) or changes (plural)

According to the MGMAT rule, sentence #1 should use a plural verb (have), since "species" is plural. And #2 should be "indicates," since pattern is singular. Can someone please clarify why the MGMAT book is right or wrong on this subject.

IMHO "a new species" is referring to a single species of sparrow not the "species" or all of the "species" sparrow.

huh.. 2nd one is clear.. it takes indicates.. as it's subject is pattern.

first one: species is singular so it has to take 'has'.. why have?? where did u get this from? rather from which page is this taken?

A new species - singular therefore "has" should be used

Many species - plural therefore "have" should be used.

"A new species" is singular, not plural. "Species" can be either singular or plural:

"...a rare species that eats only coffee beans..."

"... are two of the species which have pink feathers..."
2) "The pattern of changes that have occurred in human DNA over the millennia indicate/indicates the possibility that everyone alive today might be descended from a single female ancestor who lived in Africa sometime between 140,000 and 280,000 years ago."
--Should it be indicate or indicates, since it's preceded by "the pattern" (singular) or changes (plural).
"The pattern" is singular, so the verb should be "indicates".
