<p>why is "need not" correct? why shouldn't it be "needs not"</p>
<ol>
<li>With its 13,677 islands displayed (like jewels) on a necklace (suspending) between Asia and Australia, Indonesia (remains) one of the most (diverse) nations on Earth. </li>
</ol>
<p>This is a special case in which “need” is being used as an auxiliary verb; it functions similarly to how “must” does. For example:</p>
<p>“Bob need not mow the ceiling” or “Bob must mow the ceiling” or “Bob must not mow the ceiling.”</p>
<p>“I need not eat tonight.”</p>
<p>In these contexts, “need” does not inflect based on plurality or singularity, nor does it conjugate based on the persona (i.e., first person, second person, third person).</p>
<p>I wouldn’t call it “idiomatic,” but if you like, that coining would function practically with no hitches. Because “need” and “need not” don’t ever inflect or conjugate, it’s difficult to misuse them. Here’s the format:</p>
<p>[Subject] [need / need not] [verb conjugated to third-person singular]</p>
<p>why is “only such tasks as” correct? Shouldn’t it be “only tasks such as”? Or are both methods correct? That is what I would’ve picked out as being the error.</p>
<p>Saying “suspending” needs to be “suspended” simply because it should be parallel to “displayed” is not really correct. How would you justify “displayed,” then? By saying it must be parallel to “suspended”?</p>
<p>Both happen to end in -ed only because they are passive participles, not because they are utilizing parallel structure. That is, the islands are BEING displayed (receiving the action), NOT displaying (performing the action), and similarly, the necklace is BEING suspended, NOT suspending something else.</p>
<p>Participles come from verbs but act like adjectives. Since they are verbs, they come after the noun, not before it like adjectives do.</p>
<p>“The man, having drunk so many beers in one night, could not wake up the next morning.”</p>
<p>“Bring all the required documents.”
“Bring all the documents required.” = “Bring all the documents [that are being] required.”
“The man sleeping on the street is actually dead.”</p>
<p>If the participle ends with -ing, it is active. That is, “the man sleeping” is doing the sleeping. This seems more like a verb.
If the participle ends with -ed, it is passive. That is, “the documents required” is being required by something else. This seems more like an adjective.</p>
<p>You seem to be indicating that “being” is implicit in every present passive construction; rather, “being” is only appropriate in the present progressive. For example:</p>
<p>“Bring all the documents required” is, implicitly, either “Bring all the documents [that are] required” or “Bring all the documents [that are being] required.” </p>
<p>The former form is far more logical in that context, as it is in the original sentence. The requiring is a general action, so the simple present is correct; the present progressive is not.</p>
<p>For “With its 13,677 islands displayed (like jewels) on a necklace (suspending) between Asia and Australia, Indonesia (remains) one of the most (diverse) nations on Earth,” the simple present is, similarly, more logical.</p>
<p>I’m not confident anymore that “suspending” is incorrect there. “suspend” can be an intransitive verb, rendering the voice potentially active for the phrase; as such, “suspending” could be acceptably implicit for “that are suspending.”</p>
<p>“Suspend” as an intransitive verb does not share the relevant definition; if it is to mean “hang,” suspend must be transitive (which requires an object)</p>
<p>I just looked at the site (I had posted it without really confirming because I trusted my instinct) and it actually does have “hang” as a definition of “suspend” as an intransitive verb. However, there must be some other reason that it is there because not only is it the last definition (which doesn’t really mean anything) but because I cannot think of a sentence that utilizes it.</p>
<p>I’ve never heard “a flag suspends” but I have heard “a flag hangs”</p>
<p>@crazybandit: I justified “displayed” only because it was a given (not one of the answer choices), between that and it just ‘popping out’ I concluded it was the right answer. Not necessarily the right way to get a question correct, I do admit, but these strategies definitely help. Thank you for the discussion to clarify why.</p>
<p>Aren’t some of these of justifiable relevance?</p>
<p>Here’s the sentence again:</p>
<p>“With its 13,677 islands displayed (like jewels) on a necklace (suspending) between Asia and Australia, Indonesia (remains) one of the most (diverse) nations on Earth.”</p>
<p>Dropping the parenthesis and including everything that is otherwise merely implicit, we get (note that the subject of the verb phrase “to be suspended” is not clear, as it could be either “jewels” or “necklace”):</p>
<p>“With its 13,677 islands [that are] displayed like jewels on a necklace [that is/are suspended] between Asia and Australia, Indonesia remains one of the most diverse nations on Earth.”</p>
<p>Dropping the dependent adjective clause and the brackets, we get (note that it is clear that “like jewels on a necklace” is not part of the first dependent clause because, if it were, “as” would need to be substituted for “like” to accommodate the clause resulting from the implicit “are” in “as jewels [are [displayed]] on a necklace”):</p>
<p>“With its 13,677 islands like jewels on a necklace, Indonesia remains one of the most diverse countries in the world.”</p>
<p>It seems that, given the ambiguous subject of “suspending/suspended,” one could justify some of the definitions of its intransitive use, which would render it acceptable. It also seems that one could justify “like jewels” as incorrect if the intention of the sentence were to compare the islands’ display to the jewels’ display. If this were the case, the subject of “suspending/suspended” would have to be “necklace.”</p>
<p>Their explanation is faulty here. “like jewels” cannot modify a participle; it would have to be “as jewels” in order to accommodate the resultant, implicit clause:</p>
<p>“With its 13,677 islands that are displayed as jewels are displayed on a necklace that is suspending between Asia and Australia, Indonesia remains one of the most diverse nations on Earth.”</p>
<p>^ (A) is wrong; (B) isn’t: “that is” before “suspending” is acceptably both implicit and passive.</p>
