fossils

Pl. explain the following.

Q-Radiocarbon dating is a reliable method of determining the age of fossils, and larger fossils typically provide much more accurate readings than smaller fossils. In Marunga, which has recently built its first carbon dating laboratory, most fossils that are unearthed are small. Aiming to boost the laboratory's productivity and Marunga's reputation as a paleontology center, the government plans to fund excavations at sites known to contain large fossils.Which of the following, if true, most seriously undermines the likelihood that the government funding, if implemented, will achieve both of the cited aims?

A. Without government funding, paleontologists seeking to uncover large fossils in Marunga would need to rely heavily of private sources of investment.

B. Many of the fossils unearthed in Marunga can be approximately dated before testing them in the carbon dating laboratory.

C. Large fossils are not generally located in the same parts of Marunga as are small fossils.

D. The largest obstacle in the way of Marunga's development as a paleontology center is not funding, but availability of qualified academics.

E.The small fossils in Marunga are much older and of greater paleontological interest than large fossils in the area, which promise little in the way of advancing scientific knowledge.

IMO its D
What is OA?

Here is the reasoning from my end

in the argument the government has assumed that if the laboratory gets more large fossiles then its productivity and reputation will increase.So we are looking for an option which will weaken this.

A. Irrelevant
B. Irrelevant
C. Irrelevant because it is clearly stated that 'the government plans to fund excavations at sites known to contain large fossils'
D. Provides an alternate reason for less productivity and reputation of the laboratory hence correct
E. this talks about 'advancing scientific knowledge' not increasing 'productivity and reputation' hence not correct.

OA is E.

It has to be E.

Small Fossils have great paleontological interest --> Marunga's reputation as a paleontology center.
Large Fossils promise little in the way of advancing scientific knowledge --> Aiming to boost the laboratory's productivity (people are experienced with knowledge which increases productivity)


D it too extreme and does not handle both the aims. how can qualified academics handle reputation of the center, academics can give a faint support to laboratory's productivity.

Please explain as to why 'E' is much more appropriate than 'D'?

The two cited aims are Marunga's reputation as paleontology center and increasing labs productivity (i.e. productivity of people working in the lab). Now we need to find an answer which will weaken the conclusion that government funding for excavation sites containing large fossils is required which govt thinks will achieve both the above aims. As said in the question stem, we need to show that it is improbable that govt will achieve the aims. This can be done either by claiming that one of the aims cannot be achieved or both cannot be achieved.

As explained in the above post,

E.The small fossils in Marunga are much older and of greater paleontological interest than large fossils in the area, which promise little in the way of advancing scientific knowledge.

This says that smaller fossils are of great paleontological interest. If we can dig something out which is of interest to researchers or historians from Marunga wont it gain reputation as paleontology center. So is it not better to invest money on smaller fossils than govt spending on larger fossils. This weakens the first cited aim.

Then it has been said that (please look at the modifier phrase of "which..." it modifies large..dont be confused here) large fossils promise little in way of advancing knowledge. This shows that large fossils if excavated can not be of much importance from gaining knowledge pov. This means that smaller fossils promise better knowledge than larger. So the experience of gaining knowledge in excavating smaller fossils will be a good experience for people in lab who are performing dating. This would lead to increase in productivity as you would be well trained by that scientific knowlegde u gain.

Hope this is clear. Any other thing which you require.

Actual Stimuli:

Radiocarbon dating is a reliable method of determining the age of fossils, and larger fossils typically provide much more accurate readings than smaller fossils. In Marunga, which has recently built its first carbon dating laboratory, most fossils that are unearthed are small. Aiming to boost the laboratory's productivity and Marunga's reputation as a paleontology center, the government plans to fund excavations at sites known to contain large fossils.

How it can be interpreted while reading:

Radiocarbon dating is a reliable method of determining the age of fossils. Larger Fossils typically provide much more accurate readings than smaller fossils. But in Marunga, which has built its first carbon dating lab, most fossils that are unearthed are small. Also, Government of Marunga aims to boost the lab productivity and Marunga's reputation as a paleontology center. Therefore, it plans to fund excavations at sites known to contain large fossils.


This answers the question.

@nileshdalvi Thanks for the detailed explanation. It's clear to me now. I think the key bit,as you have pointed out,is the modifier 'which'.

Cheers
