para1
narrate the limited resources to vegetal behavior that made lots of assumption as well as observation fail to work in the old days, and how nowadays the advent of plant neurobiology shed light on the puzzle of vegetal behavior
para2
follow para1, the author praise the usefulness to plant neurobiology, not only academic side but also on the study of “cognition” field, which later be confirmed explicitly by neurobiologist that plant indeed posses this capacities
para3
to eliminate the doubts that it be too narrow the scope concern with plant intelligence, which can only be achievable by plant experts—institutional support, and this follow by the recommendation on the institutional scientific effort in para1&2 of the plant neurobiology which further raise up the future prospect in the study of vegetal behavior
1. Which one of the following most accurately expresses the main point of the passage?
(A) Plant neurobiology has deepened our understanding of the incredible complexity that underlies vegetal behavior.
see para2
Research in plant neurobiology has not only deepened our knowledge of vegetal behavior,
....this only cover part of the passage and cannot constitute the main point of the passage
(B) Thanks to recent advances in plant neurobiology, our understanding of cognition has evolved.
“recent advances in plant neurobiology” is correct, but whether “our understanding of cognition has evolved or not”
we don’t know for sure, it just prompted a critical reevaluation of “cognition” as we know from the sentences in para2
see sentence in para3
Research in plant neurobiology has not only deepened our knowledge of vegetal behavior, but has also prompted a critical
reevaluation of “cognition” as an operative term in a variety of seemingly unrelated fields, such as linguistics, philosophy, and anthropology.
(C) Advances in the field of plant intelligence require establishing an autonomous department dedicated to the study of plant neurobiology.…this one is correct, I cannot quite understand why at first and I think (A) or (D) better suit, but you had to notice the naunces
Gautam12121991The accelerated pace of discoveries involving (30) plant intelligence warrants significant institutiona lcommitment,
which can only be provided by establishing a Department of Plant Neurobiology at our university.
"Our appreciation of vegetal behavior is attainable if, but only if, we recognize the value of plant neurobiology as an autonomous discipline worthy of institutional support."
Para1 and para2 acts as premise for conclusion in para3.….I am wrong for that I miss this point in my thinking
(D) Plant neurobiology has accelerated the pace of scientific discoveries involving vegetal behavior.
I share the same thinking as
adstudy, (A)&(D) are quite similar-contender, I chose (D) at first, but as to why (D) is also incorrect
see the last sentence in para1:
Today, with the advent of plant neurobiology, scientists can finally shed light on the incredible complexity that underlies vegetal behavior.
“plant neurobiology” just shed light on “vegetal behavior”, but about its pace, whether accelerate or not, we don’t know for sure
(E) Plants possess cognitive capacities even though they lack the neural architecture that gives rise to animal cognition.
….only cover part of para3
2. Each one of the following is mentioned in the passage as an example of known vegetal behavior, EXCEPT:
(A) to process environmental input
para1
(6)we observed that plants can process informational input on humidity and light
(B) to communicate information
para1
(13)let alone communicate these hazards through biochemical cues.
(we have already suspect vegetal behavior communicate information, but cannot prove)
(C) to experience pain....correct
I chose (D) same as adstudy at first, since no direct words in the passage ever show (D) “interact through signals”
However, we should notice some indirect words imply the meaning of “interact through signals”, refer to line (5) “adaptively respond to stimuli”
I think the reason why (C) be the correct answer is in this time phrase ‘’not before long’’
see the sentence in para3, “not before long, we will discover that plants are capable of not only experiencing pain….”
so “experiencing pain”, at least for now, is still an unknown vegetal behavior
(D) to interact through signals
see para1
We assumed that plants are able to (5) adaptively respond to stimuli,
(E) to use biochemical cues
para1
(13)let alone communicate these hazards through biochemical cues.
3. The author observes that plants “lack the neural or synaptic structures that give rise to animal cognition” (lines 27-28) mainly in order to
(25) Thanks to plant neurobiologists, we now have definitive
proof that plants possess cognitive capacities even
though they lack the synaptic structures that give rise to
animal cognition.
(A) indicate a necessary precondition for cognitive function
does the neural or synaptic structures a “necessary” precondition for cognitive function?
think of “necessary” in logic
if A is necessary for B, then no A must lead to no B
if we assume A is neural or synaptic structure; B is animal cognition, but here we already know “ if A doesn’t exist, B still occur”, so B is not a necessary condition for B
(B) differentiate the cognitive abilities of plants from those of animals
out of scope
(C) explain why scientists find it difficult to attribute cognitive abilities to plants
The author mention “plants lack the neural or synaptic structures that give rise to animal cognition” is not aim at “attribute sth, attribute abilities to plants”
(D) show that certain physiological attributes are no longer sufficient to prove cognitive function
if we think of “sufficient” in logic way
“certain physiological attributes” such as “neural or synaptic structures” –A is sufficient for “cognitive”—B, we can try to negate A, but here from the sentence above we know if A doesn’t occur, B will still occur, so this is truly a “sufficient” rather than “no sufficient” condition
or think of it in another way
“no longer sufficient to prove cognitive function” is away from the topic, since here we’re talking about “the lacking of neural or synaptic structure which give rise to animal cognition”, we are not intend to prove anything related cognitive function
(E) suggest a way in which our understanding of “cognition” has changed over time…..correct
for this sentence, we know that “synaptic structures”, which is missing in the plants we study, is a definite “physiological attributes” for animal cognition, however, the plants we study still own the cognitive capacities albeit they have no these structure, this is totally divert from how people think in the past, thus the author wrote this sentence is aim at suggesting a way which our understanding of “cognition” has changed over time
4. Which one of the following most accurately describes the relationship between the second paragraph and the final paragraph?
(A) The second paragraph anticipates the objections raised in the final paragraph.
(B) The second paragraph helps to justify the course of action recommended in the final paragraph. ......correct
(C) The final paragraph supports the argument made in the second paragraph by clarifying the potential significance of an academic initiative.
(D) The second paragraph describes a controversial view that the author defends in the final paragraph.
(E) The final paragraph debates the significance of a biological phenomenon, which is described in the second paragraph.
sec para doesn’t “anticipate、argue、describe a controversial view”
the author used para2 as a premise to arrive at the conclusion in para3.
5. The passage provides information that answers each of the following questions EXCEPT:
(A) How can research in plant physiology contribute to our future understanding of vegetal behavior?…correct
refer to para3
By assembling scientists to study vegetal behavior under one roof, a department dedicated solely(only, this is the key to this choice) to plant neurobiology will be uniquely capable of addressing issues
far beyond the scope of (40) plant physiology.
(B) Has plant neurobiology altered our conception of cognition?
para 2
(20) Research in plant neurobiology has not only deepened our knowledge of vegetal behavior, but has also
prompted a critical reevaluation of “cognition” as an operative term in a variety of seemingly unrelated fields, such as linguistics, philosophy, and anthropology.
(C) What impact has the study of plant neurobiology made on other academic fields?
para 2
Research in plant neurobiology has not only deepened our knowledge of vegetal behavior, but has also prompted a critical reevaluation of “cognition” as an operative term in a variety of
seemingly unrelated fields, such as linguistics, philosophy, and anthropology.(D) How do plant neurobiologists study vegetal behavior?
para 2
Plant neurobiology studies the complex patterns of behavior of plants through information-processing (20) systems.
(E) What are some of the directions for future research in vegetal behavior?
para3
capable of addressing issues far beyond the scope of (40) plant physiology.
Not before long, we will discover that plants are capable of not only experiencing pain, but also of employing complex cost-benefit analysis to adapt and learn from their mistakes. Our appreciation of vegetal behavior is attainable if, but only if, we (45) recognize the value of plant neurobiology as an autonomous discipline worthy of institutional support.
6. Given its tone and content, from which one of the following was the passage most likely drawn?
(A) a textbook on plant neurobiology
(B) a grant application for an experimental study
(C) an editorial published in a national newspaper
(D) a strategic initiative proposed by an academic dean….correct
Can be directly inferred from the below mentioned lines -
The accelerated pace of discoveries involving (30) plant intelligence warrants significant institutional commitment, which can only be provided by establishing a Department of Plant Neurobiology at our university.
(E) a study focusing on vegetal behavior
(A)&(E) are quite confusing, but they both can’t be the best source for this passage as (D)-a strategic initiative, they’re just smaller set under the bigger picture-a strategic initiative
also, see the first sentence in para1
Biologists have long suspected that vegetal behavior is exceptionally complex, but such hypotheses were impossible to test due to limited technical resources.
and last sentence
Today, with the advent of plant neurobiology, scientists can finally shed light on the incredible complexity that underlies vegetal behavior.
rather saying the author “focus” on the study of vegetal behavior, it is better to say that this is a study “try to solve the complexity of vegetal behavior”, since we know some of its complexity still remain unresolved, see from sentence in para3:
Not before long, we will discover that plants are capable of not only experiencing pain, but also of employing complex cost-benefit analysis to adapt and learn from their mistakes.
7. Which one of the following is most analogous to the position discussed in lines 33-35?
Some of my colleagues worry that this department would have no clear rationale, because (35) its objectives are in principle achievable by plant physiologists.
- this department has no clear intention/direction—of little use-- to its study, because it is mostly achievable by plant “physiologist”
-plant physiologists itself is enough good to this study, no need other department
(A) A car manufacturer refuses to develop a new type of electric car, because the currently existing hybrid model is environmentally friendly......correct
(refuse to change because current physiologist is already good)
-we don’t need this department(electric car), since the current physiologist(hybrid car) is already enough to achieve its goal
(B) A car manufacturer refuses to develop a new type of electric car, because the cost of research and development is far greater than the potential earnings from the sale of such cars.
cost is not concern here
(C) A car manufacturer refuses to develop a new type of electric car, because such cars merely exchange one form of pollution for another, equally destructive form.
(refuse to change is because if change will be equally bad)
(D) A car manufacturer refuses to develop a new type of electric car, because there is no scientific consensus on the issue of global warming.
(refuse to change is because of no consensus, but does there any consensus exist between “this department & physiologist”? clearly not)
(E) A car manufacturer refuses to develop a new type of electric car, because the infrastructure required to support such cars is not yet available.
(refuse to change is because of no supported infrastructure)
