# Sentence Equivalence: Practice Question of the Week #12

For Sentence Equivalence, remember that there can be more than one correct answer!

Researchers who study circadian rhythms have found that the physiological processes of animals and plants are neither independent of, nor entirely ___________ external stimuli, such as light and temperature, during a given 24-hour period.

1. imperiled by
2. analogous to
3. coincident with
4. perturbed by
5. appurtenant to
6. concomitant with

If you don’t know some of the vocabulary in the answers, this is a great opportunity to learn some new definitions! I would suggest http://thefreedictionary.com, especially the section called “References in periodicals archive” (you’ll have to scroll down a bit once you look up a word) so that you can learn the words in context.  Good luck, we’ll be posting the answer(s) tomorrow!

I think the answers are E and F the explanation here is neither independent nor entirely DEPENDENT so here as Concomitant (F) – is connected somehow collaterally, and Appurtenant’ (E) means to pertain to something more important or to be added to/attached to something else.
This answer is purely by elimination

I will go with options A (Imperiled by) and D(Perturbed by). The blank should be filled by a word which means DEPENDENT. When you are going to depend on something, if its not available, you will be in danger/disturbed.

Hi,

I would go for B & F

C & F

I think answers are A (imperiled ) and D (appurtenant ), here context is talking about physiological processes,

hence ‘nor imperiled by’ means… plants and animals are not in danger with external factors

‘nor appurtenant with’ means, not getting additional support with external factors..

I think the answers are C (coincident with) and F (concomitant with). Both mean to exist or occur with something else.

‘Imperiled’ (A) means to be endangered.
‘Analagous to’ (B) means to be similar or alike in a way such that an analogy can be made.
‘Appurtenant’ (E) means to pertain to something more important or to be added to/attached to something else.
‘Perturbed’ (D) means to be disturbed or made anxious by something.

Does Revised GRE have negative marking

• Chris August 16, 2011 at 5:49 pm #

There is no penalty for guessing on the Revised GRE. ETS, at least to the best of my knowledge, has not stated this is the case. However, my hunch is that much of the question overhaul on the Revised GRE was to eliminate random guessing. That’s why there are now questions like the Multiple Answer Questions or the Triple-Blank Text Completions. The probability of guessing correctly on these question is so low that there is now no reason to discourage guessing by invoking the dreaded penalty score. (This especially holds true for Numeric Entry).

Therefore, definitely guess on every question and leave no empty box unfilled.
