Archeologists have discovered three sites showing conclusive evidence for the mastery of fire in Tanzania, from a period slightly after the time that Homo habilis was present in Africa. These sites clearly were founded by Homo erectus, the descendent species of Homo habilis that migrated north, out of Africa and into Asia. Homo erectus was known to have mastered fire, from ample evidence at sites in Asia. There is no reason to attribute mastery of fire to Homo ergaster, the descendent species of Homo habilis that remained in Africa.
Q. Which of the following is an assumption on which the argument depends?
  • a)
    Before their migration, Homo erectus occupied African territory as far south as Tanzania.
  • b)
    The strain of migration provided the selective pressure motivating Homo erectus‘ mastery of fire.
  • c)
    Homo ergaster would not have derived as much benefit from the mastery of fire as did Homo erectus.
  • d)
    Homo ergaster inherited all cultural knowledge from Homo habilis, a species that did not have mastery of fire.
  • e)
    Homo ergaster did not occupy regions as far south as Tanzania until well after the time of these three sites.
Correct answer is option 'A'. Can you explain this answer?

Archeologists have discovered three sites showing conclusive evidence ...
Remains of prehistoric fire were found in Tanzania. The author says that Homo erectus made these fires, and that there’s no reason to assume Homo ergaster did. What is a necessary assumption?
The credited answer is choice (A). Homo erectus had to be as far south as Tanzania—if they were not, there would be no way they could have made those fires there, which would seem to indicate that Homo ergaster made them after all. Negating this statement devastates the argument, which is a confirmation that we have an assumption.
Whatever might have caused Homo erectus to master fire doesn’t clarify who made those fires in Tanzania: Homo erectus or Homo ergaster? Choice (B) is not correct.
Suppose Homo ergaster would have derived as much benefit from the master of fire as did the Homo erectus, or even more benefit. That fact, by itself, would imply nothing about which one of these species created those fires in Tanzania. Denying this doesn’t change the validity of the argument. Choice (C) is not correct.
Choice (D) is intriguing, because it may be true. Both Homo erectus and Homo ergaster evolved from Homo habilis, so it’s quite likely that the Homo habilis was the sole source of cultural knowledge for either of these species. BUT, we know that Homo erectus, presumably without the benefit of cultural knowledge about fire, was able to master fire. If Homo erectus did that, why couldn’t Homo ergaster? In other words, the limits of the cultural knowledge inherited does not necessarily set limits on what these human species could achieve. Therefore, we can draw no conclusion with respect to this argument. Choice (D) is not correct.
If Choice (E) were true, it would support the argument, but a supporting statement is not necessarily an assumption. We have to use the Negation Test. Suppose Homo ergaster was all over in Tanzania, before & during & after the time that those fires were created. Would that prove Homo ergaster started those fires? Not necessarily. It could still be true that both Homo ergaster and Homo erectus occupied that region, that only the latter had mastered fire, and therefore, that the later had to start those fires in Tanzania. Thus, we can deny choice and it doesn’t necessarily contradict the argument. Therefore, it is not an assumption. Choice (E) is not correct.

Directions: Read the Passage carefully and answer the question as follow.Archaeology as a profession faces two major prob-lems. First, it is the poorest of the poor. Only paltrysums are available for excavating and even less is avail-able for publishing the results and preserving the sites(5) once excavated. Yet archaeologists deal with pricelessobjects every day. Second, there is the problem of illegalexcavation, resulting in museum-quality pieces beingsold to the highest bidder.I would like to make an outrageous suggestion that(10) would at one stroke provide funds for archaeology andreduce the amount of illegal digging. I would proposethat scientific archeological expeditions and govern-mental authorities sell excavated artifacts on the openmarket. Such sales would provide substantial funds for(15) the excavation and preservation of archaeological sitesand the publication of results. At the same time, theywould break the illegal excavator’s grip on the market,thereby decreasing the inducement to engage in illegalactivities.(20) You might object that professionals excavate toacquire knowledge, not money. Moreover, ancient arti-facts are part of our global cultural heritage, whichshould be available for all to appreciate, not sold to thehighest bidder. I agree. Sell nothing that has unique(25) artistic merit or scientific value. But, you might reply,everything that comes our of the ground has scientificvalue. Here we part company. Theoretically, you may becorrect in claiming that every artifact has potential scien-tific value. Practically, you are wrong.(30)I refer to the thousands of pottery vessels and ancientlamps that are essentially duplicates of one another. Inone small excavation in Cyprus, archaeologists recentlyuncovered 2,000 virtually indistinguishable small jugs ina single courtyard, Even precious royal seal impressions(35) known as/melekh handles have been found in abun-dance---more than 4,000 examples so far.The basements of museums are simply not largeenough to store the artifacts that are likely to be discov-ered in the future. There is not enough money even to(40) catalogue the finds; as a result, they cannot be foundagain and become as inaccessible as if they had neverbeen discovered. Indeed, with the help of a computer,sold artifacts could be more accessible than are thepieces stored in bulging museum basements. Prior to(45) sale, each could be photographed and the list of thepurchasers could be maintained on the computer Apurchaser could even be required to agree to return thepiece if it should become needed for scientific purposes.It would be unrealistic to suggest that illegal digging(50) would stop if artifacts were sold on the open market.But the demand for the clandestine product would besubstantially reduced. Who would want an unmarkedpot when another was available whose provenance wasknown, and that was dated stratigraphically by theprofessional archaeologist who excavated it?Q.The author’s argument concerning the effect of the official sale of duplicate artifacts on illegal excavation is based on which of the following assumptions?

The two construction periods at Aztec, New Mexico, as indicated by the modern tree-ring dating, are corroborated nicely by other evidence found by archaeologist Earl H. Morris in the 1920s that Aztec actually was built by one group of people, abandoned, and then reoccupied at a later date by a slightly different group of people. Throughout all the rooms he dug during his early 20th century excavations, he found sterile layers of windblown sand and ruined debris from falling walls and ceilings. In this debris and under the sand, he found Chaco-like pottery and artifacts. In addition, there were surprisingly few burial sites. Even today, archeologists have located few Chaco-type burials in Chaco Canyon itself. Whatever the burial customs of the Chaco people may have been, they have eluded archeologists for many decades. The absence of burials of this period at Aztec is a clue that probably a group of Chaco-like people, bearing the distinctive Chaco culture, may actually have moved into the Aztec area.Granting that the local sandstone was not quite as easily worked as that at Chaco, the large-size rooms, the high ceilings, the banded-veneer masonry walls, the large doorways, and other techniques used were very similar to the architectural techniques of the Chaco area. Overlying the Chaco debris and sterile sand layers, Morris found pottery, household utensils, and burials characteristic of the classic Mesa Verde Perioda period which occurred later than the great Chaco Period. In addition, there were obvious architectural signs of rebuilding and remodeling within the pueblo. Large Chaco-type rooms had been made smaller by wattle-and-daub partition walls, while doorways had been shortened and narrowed more like the ones at Mesa Verde. Thus there were two definite periods of occupation at Aztec, one by a Chaco-like people and one by a Mesa Verde-type people.The author of the passage likely mentions both Morris and the tree-ring dates in order to
