At the end of the Triassic period, there was a mass extinction.
The reading argues about the extinction of the vast majority species at the end of the Triassic era. The author listed three factors to support the idea that some events caused this extinction. However, the speaker finds all the ideas dubious and presents some evidence to refute all of them.
First, the reading mentioned that decreasing sea level is one of the possible reasons. Due to the fluctuation of sea level, many species that lived in shallow or coastal water died. In contrast, the speaker rebuts this reason and stats that it is true in that period the sea level declines but it happened gradually not suddenly. Hence, the species adapted to this change little by little and it could not be the possible reason.
Second, the passage reading points out that climate change is responsible. To clarify this reason, volcanic activity produced lots of sulfur dioxide that caused the temperature decline and the climate becomes cool. On the contrary, the speaker casts doubt on this issue and asserts that global cooling is not deniable but the increase of SO2 cannot be the reason because SO2 is still present in the atmosphere.
Finally, the author proposes that the asteroids hit the earth and destroyed many species. On the other hand, the speaker rejects this reason too and states that no collision of steroids found during that period, also, all evidence related to 12 million years ago before extinction.
Comments
Would it be possible to
Would it be possible to explain "unique words" and also "subordinate clause"?
thanks in advance
one example for 'unique words
one example for 'unique words':
'the teacher and the student are in the class'
so the unique words are: 'the, teacher, student, and, are, in, class'. 'the' is repeated 3 times.

What Is a Subordinate Clause? (with Examples)
A subordinate clause (or dependent clause) is a clause that cannot stand alone as a complete sentence because it does not express a complete thought.
Like all clauses, a subordinate clause has a subject and verb.
Examples of Subordinate Clauses
Here are some examples of subordinate clauses (shaded). You will notice that none of the shaded clauses could stand alone as a sentence. This is how a subordinate clause (or a dependent clause) is different from an independent clause.
She had a pretty gift for quotation, which is a serviceable substitute for wit. (W Somerset Maugham, 1874-1965)
A musicologist is a man who can read music but can't hear it. (Sir Thomas Beecham, 1879-1961)
Always be nice to those younger than you because they are the ones who will be writing about you. (Cyril Connolly, 1903-1974)
Personally I'm always ready to learn, although I do not always like being taught. (Sir Winston Churchill, 1874-1965)
Types of Subordinate Clause
Subordinate clauses can act as adjectives, adverbs, or nouns.
The Adjective Clause. Here is an example of a subordinate clause acting as an adjective:
The bull that charged us is back in the field.
(The subordinate clause that charged us describes the bull. It is an adjective clause.)
The Adverbial Clause. Here is an example of a subordinate clause acting as an adverb:
I fished until the sun went down.
(The subordinate clause until the sun went down modifies the verb to fish. It is an adverbial clause.)
The Noun Clause. Here is an example of a subordinate clause acting as a noun:
Whoever dislikes the new timings is more than welcome to leave.
(The subordinate clause Whoever dislikes the new timings is the subject of this sentence. It is a noun clause.)
The Link between a Subordinate Clause and an Independent Clause
When a subordinate clause is used as an adjective or an adverb, it will usually be part of a complex sentence (i.e., a sentence with an independent clause and at least one subordinate clause).
The link between a subordinate clause and an independent clause will often be a subordinating conjunction or a relative pronoun. For example:
I fished until the sun went down.
The bull that charged us is back in the field.
