Passage

Calvaria major is a rare but once-abundant tree found on the island of Mauritius, which was also home to the dodo, a large flightless bird that became extinct about three centuries ago. In 1977 Stanley Temple, an ecologist whose investigation of Calvaria major was a sidelight to his research on endangered birds fertile but that Temple assumed could no longer germinate, given his failure to find younger trees.

The temporal coincidence between the extinction of the dodo and what Temple considered the last evidence of natural germination of Calvaria major seeds led him to posit a causal connection. Specifically, he hypothesized that the fruit of Calvaria major had developed its extremely thick-walled pit as an evolutionary response to the dodo’s once been adaptive, Temple maintained, became a lethal imprisonment for the seeds after the dodo vanished.

Although direct proof was unattainable, Temple did offer some additional findings in support of his hypothesis, which lent his argument a semblance of rigor. From studies of other birds, he estimated the abrasive force generated within a dodo’s gizzard. Based on this estimate and on test results determining the crush-resistant strength of abraded yet intact. Three of these sprouted when planted, which he saw as vindicating his hypothesis.

Though many scientists found this dramatic and intriguing hypothesis plausible, Temple’s proposals have been strongly challenged by leading specialists in the field. Where Temple had found only thirteen specimens of Calvaria major, Wendy Strahm, the foremost expert on the plant ecology of Mauritius, has identified hundreds, many far younger than three centuries. disease and damage done by certain nonindigenous animals introduced onto Mauritius in the past few centuries.

Answer choices

  1. Out of Scope8% picked this

    despite his attempts to use strict scientific methodology, Temple's experimental findings regarding Calvaria major pits were not carefully derived and thus merely

    Out of Scope: strict methodology Out of Scope: not carefully derived We can't really support these specific claims that he attempted to use strict scientific methodology or that his experimental findings were not carefully derived. The passage is just saying that Temple had a couple pieces of circumstantial evidence that corroborated his theory, so it lent his theory "the aroma of being true".

  2. Too Strong: impossible / most exact5% picked this

    direct proof of a hypothesis of the sort Temple was investigating is virtually impossible to obtain, even with the

    We're told that direct proof was unattainable for the hypothesis he was pitching, that's it. We can't amplify that into some extreme idea that "for this sort of hypothesis, direct proof is always virtually impossible, even with the most exact measurements and observations". This answer should probably feel inherently trappy since it's grabbing language from the beginning of the sentence they're pointing us to.

  3. Way Too Specific10% picked this

    in contrast to Temple's secondhand information concerning the age of the thirteen overmature Calvaria major trees he found, his experiments with turkeys and other

    The expression "semblance of rigor" is not specifically tied to 13 overmature trees or to experiments with turkeys. Temple had a hypothesis (a causal storyline) for why a certain tree was endangered. He gave this hypothesis a semblance of rigor (he gave it some slight corroboration) by estimating the abrasive force of the dodo's gizzard and by feeding pits from the endangered trees to turkeys. The author was not using "semblance of rigor" to convey a big gap in the scientific credibility between the info Temple had about the trees and the experiments he did with the turkeys.

  4. Correct70% picked this

    in his experimentation on Calvaria major pits, Temple produced quantitative experimental results that superficially appeared to bolster the

    Why this is right

    "Superficially appeared to bolster the credibility of his hypothesis" is the gist we were looking for. Naturally, because this is a correct answer, the part we like is hidden towards the back end of the answer choice. Can we sign off on this front end wording? Did Temple produce quantitative experimental results? Yes, he estimated the abrasive force of a dodo's gizzard, that's quantitative. He also had test results determining the crush-resistant strength of Calvaria major pits. That's also a calculable value.

  5. Too Positive6% picked this

    although the consensus among experts is that Temple's overall conclusion is mistaken, the scientific precision and the creativity

    The author is making a concession toward Temple, by saying "semblance of rigor". But it's not as positive as this answer is making it out to be. It's more like, "he wasn't a total clown", not like, "his precision and creativity are admirable!" The phrase "a semblance of rigor" is not really a compliment. It's saying, "This hypothesis was not totally unsupported. He was able to make it look like what he was doing had actual scientific precision. (But it did not)." The author doesn't say anything complimentary about Temple in the whole passage. The closest it comes is "dramatic and intriguing", but that's not necessarily a compliment when we're talking about science.
