There is a sentence that is missing in the paragraph below. Look at the paragraph and decide in which blank (option 1, 2, 3, or 4) the following sentence would best fit.

Sentence: On the other side, when I saw the surrounding environment spread far and wide, I actually used to get great surprise and joy.

The mountains still draw my heart from far away. (1)_________. In childhood, when I saw a mountain or a hill from a distance, it seems like they are calling me mountains and mounds. To the rough-dry mountains of a distance of two miles, I used to go away by gallop several times. (2) _________. Then raised questions in my mind, the people of the cold and lush mountains talk about, they go there in the summer, they will not know what kind? (3)__________ The desire to see those mountains from the beautiful moments of childhood could be completed in the summer holidays last year. (4)__________ In fact, it was actually a new and enjoyable experience for me.

There is a sentence that is missing in the paragraph below. Look at the paragraph and decide in which blank (option 1, 2, 3, or 4) the following sentence would best fit.

Sentence: This meant it competed for prey with smaller carnivores.

(1)_________. To conserve species and restore ecosystems effectively we have to understand historical context. The thylacine was an apex predator, at the top of the food chain, albeit one that hunted smaller prey relative to its size. (2)________. Thylacines may have shaped the behaviour and reduced the abundance of devils and quolls and their prey, wallabies and pademelons. (3)_______ This competition thus affected how the devil and quolls evolved in terms of prey size and the size of their canine teeth. (4)________ Wedge-tailed eagles are probably the closest analogue now to the thylacine.

The majority of the time fossils are dated using relative dating techniques. Using relative dating the fossil is compared to something for which an age is already known.
For example, if you have a fossil trilobite and it was found in the Wheeler Formation. The Wheeler Formation has been previously dated to approximately 507-million-year-old, so we know the trilobite is also about 507 million years old.
Scientists can use certain types of fossils referred to as index fossils to assist in relative dating via correlation. Index fossils are fossils that are known to only occur within a very specific age range. Typically, commonly occurring fossils that had a widespread geographic distribution such as brachiopods, trilobites, and ammonites work best as index fossils. If the fossil you are trying to date occurs alongside one of these index fossils, then the fossil you are dating must fall into the age range of the index fossil.
Sometimes multiple index fossils can be used. In a hypothetical example, a rock formation contains fossils of a type of brachiopod known to occur between 410 and 420 million years. The same rock formation also contains a type of trilobite that was known to live 415 to 425 million years ago. Since the rock formation contains both types of fossils the age of the rock formation must be in the overlapping date range of 415 to 420 million years.
Studying the layers of rock or strata can also be useful. Layers of rock are deposited sequentially. If a layer of rock containing the fossil is higher up in the sequence that another layer, you know that layer must be younger in age. If it is lower in sequence it’s of a younger age. This can often be complicated by the fact that geological forces can cause faulting and tilting of rocks.
Unlike relative dating method absolute dating which is used to determine a precise age of a rock or fossil through radiometric dating methods. This uses radioactive minerals that occur in rocks and fossils almost like a geological clock. It’s often much easier to date volcanic rocks than the fossils themselves or the sedimentary rocks they are found in. So, often layers of volcanic rocks above and below the layers containing fossils can be dated to provide a date range for the fossil containing rocks.
The atoms in some chemical elements have different forms, called isotopes. These isotopes break down at a constant rate over time through radioactive decay. By measuring the ratio of the amount of the original (parent) isotope to the amount of the (daughter) isotopes that it breaks down into an age can be determined.
We define the rate of this radioactive decay in half-lives. If a radioactive isotope is said to have a half-life of 5,000 years that means after 5,000 years exactly half of it will have decayed from the parent isotope into the daughter isotopes. Then after another 5,000 years half of the remaining parent isotope will have decayed.
While people are most familiar with carbon dating, carbon dating is rarely applicable to fossils. Carbon-14, the radioactive isotope of carbon used in carbon dating has a half-life of 5730 years, so it decays too fast. It can only be used to date fossils younger than about 75,000 years. Potassium-40 on the other hand has a half like of 1.25 billion years and is common in rocks and minerals. This makes it ideal for dating much older rocks and fossils.

Which of the following questions is NOT answered by the author in the given passage?

There is a sentence that is missing in the paragraph below. Look at the paragraph and decide in which blank (option 1, 2, 3, or 4) the following sentence would best fit.

Sentence: We do not yet know how it is going to be assimilated into our lives.

There is no denying that an ultra-smart AI — let’s not call it AGI yet although it spooked a Google engineer so much that he called it sentient — has arrived. (1)_______. No one knows, not even Open AI CEO Sam Altman, whose company is behind GPT. (2)________But the way it’s moving, it is fairly safe to predict that AI tools like ChatGPT, Bard and Mid Journey are going to be part of the fabric that will enfold around our 21st-century world in a few years from now. (3)_______ The possibilities are endless and even if only some of them come true, our world will be changed in a fundamental way. (4)________ somewhat like how it was changed when humans realised they could control and master fire, or the day when someone figured out wheel, or in that year recently when Tim-Berners Lee wove his World Wide Web.

Most North Americans think minimal about American Indian culture and history. Researchers have concentrated such issues, yet they have not succeeded in broadcasting their decisions generally. Subsequently, it is as yet not generally realized that American Indians have epics, that they performed plays sometime before Europeans showed up, and that they practised politics and carried on the exchange system.

One way to gain a fuller appreciation of this rich culture is to examine American Indian poetry, for poetry is in all cultures the most central and articulate of the arts. It is especially important that we study American Indian poetry as this poetry can create a context that gives cohesive expression to the crafts, the artifacts, and the isolated facts that many Americans have managed to notice willy-nilly. Even a survey of American Indian poetry reveals a range of poetic thought and technique that defies easy generalization. Jarold Ramsey hazards a summary, however, which serves at least to give the uninitiated reader some sense of what American Indian poetry is like. Overall, he writes, it represents “an oral, formulaic, traditional, and anonymous art form,” whose approach is to emphasize the “mythic and sacred” components of reality. It “flourished through public performances... by skilled recitalists whose audiences already knew the individual stories” and valued the performers for their “ability to exploit their material dramatically and to combine them? their stories? in longer cycles” rather than for their “plot invention.” Because this poetry belongs to highly ethnocentric tribal peoples, whose cultures “we still do not know much about,” it “is likely to seem all the terser, even cryptic.”

American Indian poetry has another feature that Ramsey ignores: it is always functional. Whether sung, chanted, or recited; whether performed ceremonially, as entertainment, or as part of a task such as curing a patient or grinding corn; or whether recited individually or by a group, it is always fully woven into the fabric of ordinary life.

For complicated reasons, American Indian poetry has basically been ignored by non-Indian cultures. Kenneth Lincoln writes that failure to hear American Indian voices results “partly...from the tragedies of tribal dislocation, partly from mistranslation, partly from misconceptions about literature, partly from cultural indifference.” Brian Swann suggests an additional explanation: tribal poetry is oral, whereas Europeans arrived in the New World with a deeply ingrained belief in the primacy of the written word. As a result, European settles found it hard to imagine that poetry could exist without written texts and thus that the American Indians had achieved something parallel to what Europeans called literature long before Europeans arrived. As a consequence, Europeans did not fully respond to the rich vitality of American Indian poetry.

Which of the following features of American Indian poetry has NOT got any mentions in the passage?
