Archaeologists working in two recently discovered limestone

Hi dpo28, I will try that.

Q4 asks to identify a situation which will negate the possibility mentioned by author in the passage. Now lets take each option individually and try to decipher:

A. The use of brushes made from animal hair did not become a common practice until about 6,000 years ago.
-> The use of brush became a common practice only 6000 years ago but it could have been used by a few "uncommon" artists before that, and hence, this does not undermines or negates author's point convincingly. Hence this is incorrect option.

B. Stones found in a nearby cave have been painted exclusively with animal figures.
-> The paintings found in a nearby cave does not negate the possibility that the ones found in the cave of importance in the passage are not unusual. The line "Hunters, warriors, and hunted animals, the typical subjects of cave art, are largely absent from these works" states "largely" which gives a room for "some" of the paintings to have animal figures as well. This as well is a incorrect option.

C. A chemical analysis shows that some of the paintings contain no gypsum, manganese, or malachite.
-> Again use of "some" in this option leaves a gap for possibility of use of above metals in the paint of some of the "other" paintings. Conclusion, this is a incorrect option.

D. To show that someone had died at the approximate age shown in a painting, the artists who created the stone paintings made a mark on the head of the figure by chipping the stone.
-> Now, if we consider this to be true, please note the option doesn't have any speculative or approximate word, likes of "some", "most", "largely" or any other been used in previous options. If this statement is considered to be true (read absolute truth because of no approximate or speculative word), the possibility of paintings depicting family trees becomes questionable because the mark which was considered to identify a individual in childhood and adulthood can not be so. Instead, it depicts the child died at that approximate age and hence can not be painted for his/her adulthood and so the reasoning is flawed that paintings represent family tree. Hence this is a correct answer.

E. Carbon-dating reveals that the stone paintings were created over a period of 200 years.
-> This option states a period over which the paintings were created, but doesn't provide the age of the paintings. It could be 5500-5700 or it could be 6200-6400 years ago and hence the possibility of the paintings ageing more than 6000 years can not be neglected straight away. This is incorrect option as well.

I chose C for qn 1 and A for qn3.
can someone explain why they are wrong?

I am not expert,but still I think it should be option D for Q1, since "Though facial features are rarely distinct..."

1. Which of the following is mentioned in the passage as an unusual feature of the stone paintings?
E. The overlapping presentation of the pieces

The important line here is: The paintings are unusual in their medium, manner of display, and subject matter. So the answer could be any of these three things. The author then elaborates on each of these three elements in the next few sentences.

The medium: the paintings are on stones

The manner of display: Some of the pieces are stacked, while others are arranged upright in an overlapping pattern

The subject matter: domestic scenes

The only one of these three elements to appear in the answer choices is the manner of display - the overlapping pattern,

2. The author of the passage is especially interested in

A. the possibility that the paintings trace the lineage of a family
However, it is the purpose of the paintings that is the most curious.

3. The primary purpose of the passage is to
C. detail some of the reasons that the discovery of the stone paintings is of considerable interest


4. Which of the following, if true, would most undermine a possibility mentioned by the author of the passage?
D. To show that someone had died at the approximate age shown in a painting, the artists who created the stone paintings made a mark on the head of the figure by chipping the stone. --- it provides an alternate reason for the presence of mark
A number of the paintings appear to feature some of the same people, and it is tempting to think of these works as family portraits. Indeed, one figure, seen as a child with a mark on its forehead—the stone has actually been chipped away to represent the mark—is shown in other paintings as a young person and as an adult with the same mark.

Hi there,

I believe the reason why choice D is the correct answer is because in the last paragraph, it mentions the possibilities of the reason why the paintings were created. The question refers to those possibilities of Hunting or Domestic life or family tree. I think here it is asking about the possibility of the purpose

Although there were no tools found in the area, the fineness of the lines indicates that the animal hair brushes were sophisticated. The paints were painstakingly ground and mixed with binding materials such as vegetable and animal oils. Gypsum, manganese, malachite at and other minerals. In some cases, the Artist (Dr Linus Mendoza of the international association of speleologists) studied the paintings and believes that stypical similarities and differences are indicative of the work of three artists.
But the topic of the pictures is the most interesting. Conventional wisdom argues that cave hunting scenes were designed to give supernatural aid during actual hunts, or that prehistoric shamans had painted figures and designs as a way to draw power from the cave. It might also be that the household scenes are intended to ensure good luck like hunting. While facial features are rarely distinctive, the paintings display contentment, or at least lack of conflict.

Can someone please explain why C not D is the correct answer for Q5 ? I thought D was the most obvious answer.
How can we derive that it was evidence regarding "origin"
