Archaeologists use technology to analyze ancient sites. It is likely that this technology will advance considerably in the near future, allowing archaeologists to gather more information than is currently possible. If they study certain sites now, they risk contaminating or compromising them for future studies. Therefore, in order to maximize the potential for gathering knowledge in the long run, a team of archaeologists plans to delay the examination of a newly excavated site.
Which of the following would be most useful to investigate for the purpose of evaluating the plan’s prospects for achieving its goal?
A. Whether any of the contents of the site will significantly deteriorate before the anticipated technology is available
B. Whether there will continue to be improvements on the relevant technology
C. Whether the team can study a site other than the newly excavated site for the time being
D. Whether the site was inhabited by a very ancient culture
E. Whether the anticipated technology will damage objects under study

Understanding the passage
Archaeologists use technology to analyze ancient sites. • To analyze ancient sites, archaeologists use technology.
It is likely that this technology will advance considerably in the near future, allowing archaeologists to gather more information than is currently possible.
• It is possible that the technology used for analyzing ancient sites will greatly develop in the future.
• Once there is a development in technology, it will allow archaeologists to collect more information from ancient sites than they can now.
• Inference: Currently, archaeologists are not able to collect as much information as the technological advances in the near future can provide from ancient sites.
If they study certain sites now, they risk contaminating or compromising them for future studies.
• If the archaeologists’ study certain sites now, they might contaminate or jeopardize their study of these sites in the future because the current technology is not sufficient to help analyze the ancient site to the extent that would be possible in the future using the developed technology.
• Note the word “certain” used in the sentence; we can understand from the use of this word that not all sites are prone to the risk of contamination or compromise from future studies.
Therefore, in order to maximize the potential for gathering knowledge in the long run, a team of archaeologists plans to delay the examination of a newly excavated site.
• Since it is not possible to gather “more” information using the current technology, to maximize the possibility of gathering as much knowledge as possible in the long run, with the use of the soon-to-be-available technology, a team of archaeologists has planned to postpone the examination of the newly excavated site.
Conclusion: A team of archaeologists has planned to postpone the examination of newly excavated sites to maximize the potential for gathering knowledge in the long run, with the use of the soon-to-be-available technology.
Pre-thinkingFalsification scenarioIn what scenario – would a team of archaeologists
NOT be able to maximize their potential for gathering knowledge in the long run by postponing the examination of newly excavated sites.
Given that:(i) Technology is used by archaeologists to examine ancient sites.
(ii) There is a chance that the technology will develop considerably in the near future.
(iii) The developed technology will help archaeologists obtain more information from the sites than they can obtain currently.
(iv) If the archaeologists analyze certain ancient sites now, they might contaminate or tamper with these sites, jeopardizing future study of these sites.
Though ProcessThe reasoning of the author is based on the development of certain technology, which, once developed, will help archaeologists gather more information from ancient sites. Thus, the archaeologists have decided to postpone the examining the newly excavated site now as studying them sooner may contaminate and jeopardize future observations.
Falsification condition: What if the newly excavated site is damaged due to other factors before the new technology is developed?
If the newly excavated site is damaged due to corrosive weather, pollution, etc. then the archaeologists will not be able to extract more information using the soon-to-be-available technology. Therefore, the author’s conclusion will break.
Assumption: The site will not undergo any change or damage until the new technology becomes available in the future.
Answer Choice AnalysisA. Whether any of the contents of the site will significantly deteriorate before the anticipated technology is available
CORRECT• This evaluation question is in line with our pre-thinking assumption, which states that the site will not undergo any change or damage until the soon-to-be-developed technology is available.
• Variance test
o Yes – The site will go through significant deterioration before the anticipated technology is available.
o In this case, our belief in the conclusion of the author is weakened.
o No - The site will not go through significant deterioration before the anticipated technology is available.
o In this case, our belief in the conclusion of the author is strengthened.
B. Whether there will continue to be improvements on the relevant technology
INCORRECT• The answer to this question is already provided in the passage.
• This information, however, does not impact the conclusion. Therefore, this choice is out of scope.
C. Whether the team can study a site other than the newly excavated site for the time being
INCORRECT• Even if the team can study another site, for the time being, it does not affect the plans for the newly excavated site. Thus, this choice is incorrect.
D. Whether the site was inhabited by a very ancient culture
INCORRECT• It is already given that archaeologists examine ancient sites. Also, this information does not affect the conclusion.
E. Whether the anticipated technology will damage objects under study
INCORRECT• The passage already states that the anticipated technology will allow archaeologists to gather more information than they currently can. Therefore, we cannot falsify this information in the variance test.
