Bread is one of the oldest prepared foods. Evidence from 30,000 years ago in Europe revealed starch residue on rocks used for pounding plants. It is possible that during this time, starch extract from the roots of plants, Such as cattails and ferns, was spread on a flat rock, placed over a fire and cooked into a primitive form of flatbread. Around 10,000 BC, with the dawn of the Neolithic age and the spread of agriculture, grains became the maninstay of making bread.In 1961 the Chorleywood bread process was developed, which used the intense mechanical working of dough to dramatically reduce the fermentation period and the time taken to produce a loaf. The process, whose high-energy mixing allows for the use of lower protein grain, is now widely used around the world in large factories. As a result, bread can be produced very quickly and at low costs to the manufacturer and the consumer. Recently, domestic bread machines that automate the process of making bread have becom popular

Life originated in the early seas less than a billion years after Earth was formed. Yet another three billion years were to pass before the first plants and animals appeared on the continents. Life's transition from the sea to the land was perhaps as much of an evolutionary challenge as was the genesis of life.

What forms of life were able to make such a drastic change in lifestyle? The traditional view of the first terrestrial organisms is based on mega fossils — relatively large specimens of essentially whole plants and animals. Vascular plants, related to modern seed plants and ferns, left the first comprehensive mega fossil record. Because of this, it has been commonly assumed that the sequence of terrestrialization reflected the evolution of modern terrestrial ecosystems. In this view, primitive vascular plants first colonized the margins of continental waters, followed by animals that fed on the plants, and lastly by animals that preyed on the plant-eaters. Moreover, the mega fossils suggest that terrestrial life appeared and diversified explosively near the boundary between the Silurian and the Devonian periods, a little more than 400 million years ago. Recently, however, paleontologists have been taking a closer look at the sediments below this Silurian-Devonian geological boundary. It turns out that some fossils can be extracted from these sediments by putting the rocks in an acid bath. The technique has uncovered new evidence from sediments that were deposited near the shores of the ancient oceans — plant microfossils and microscopic pieces of small animals. In many instances the specimens are less than one-tenth of a millimeter in diameter. Although they were entombed in the rocks for hundreds of millions of years, many of the fossils consist of the organic remains of the organism.

These newly discovered fossils have not only revealed the existence of previously unknown organisms, but have also pushed back these dates for the invasion of land by multicellular organisms. Our views about the nature of the early plant and animal communities are now being revised. And with those revisions come new speculations about the first terrestrial life-forms.

According to the passage, what happened about 400 million years ago?

A. Many terrestrial life-forms died out

B. New life-forms on land developed at a rapid rate

C. The mega fossils were destroyed by floods

D. Life began to develop in the ancient seas

Thông tin: Life's transition from the sea to the land was perhaps as much of an evolutionary challenge as was the genesis of life.

Dịch nghĩa: Quá trình chuyển đổi của cuộc sống từ biển vào đất có lẽ cũng là một thách thức tiến hóa như là nguồn gốc của sự sống.

Phương án A. The evolution of terrestrial life was as complicated as the origin of life itself = Sự tiến hóa của sự sống trên cạn cũng phức tạp như nguồn gốc của sự sống, lợi nhuận; là phương án chính xác nhất.

B. The discovery of microfossils supports the traditional view of how terrestrial life evolved = Việc phát hiện ra vi cổ ủng hộ quan điểm truyền thống của cuộc sống về việc cuộc sống trên mặt đất phát triển như thế nào.

Việc phát hiện ra vi cổ không ủng hộ quan điểm truyền thống mà phản bác nó.

C. New species have appeared at the same rate over the course of the last 400 million years = Nhiều loài mới đã xuất hiện ở tốc độ tương tự trong quá trình của 400 triệu năm trước.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 44 to 50.

Life originated in the early seas less than a billion years after Earth was formed. Yet another three billion years were to pass before the first plants and animals appeared on the continents. Life's transition from the sea to the land was perhaps as much of an evolutionary challenge as was the genesis of life.

What forms of life were able to make such a drastic change in lifestyle? The traditional view of the first terrestrial organisms is based on mega fossils — relatively large specimens of essentially whole plants and animals. Vascular plants, related to modern seed plants and ferns, left the first comprehensive mega fossil record. Because of this, it has been commonly assumed that the sequence of terrestrialization reflected the evolution of modern terrestrial ecosystems. In this view, primitive vascular plants first colonized the margins of continental waters, followed by animals that fed on the plants, and lastly by animals that preyed on the plant-eaters. Moreover, the mega fossils suggest that terrestrial life appeared and diversified explosively near the boundary between the Silurian and the Devonian periods, a little more than 400 million years ago. Recently, however, paleontologists have been taking a closer look at the sediments below this Silurian-Devonian geological boundary. It turns out that some fossils can be extracted from these sediments by putting the rocks in an acid bath. The technique has uncovered new evidence from sediments that were deposited near the shores of the ancient oceans — plant microfossils and microscopic pieces of small animals. In many instances the specimens are less than one-tenth of a millimeter in diameter. Although they were entombed in the rocks for hundreds of millions of years, many of the fossils consist of the organic remains of the organism.

These newly discovered fossils have not only revealed the existence of previously unknown organisms, but have also pushed back these dates for the invasion of land by multicellular organisms. Our views about the nature of the early plant and animal communities are now being revised. And with those revisions come new speculations about the first terrestrial life-forms.

What can be inferred from the passage about the fossils mentioned in lines 17-20?

A. They have not been helpful in understanding the evolution of terrestrial life

B. They were found in approximately the same numbers as vascular plant fossils

C. They are older than the mega fossils

D. They consist of modern life-forms

Đáp án C

Giải thích: The technique has uncovered new evidence from sediments that were deposited near the shores of the ancient oceans — plant microfossils and microscopic pieces of small animals … These newly discovered fossils have not only revealed the existence of previously unknown organisms, but have also pushed back these dates for the invasion of land by multicellular organisms.

Dịch nghĩa: Kỹ thuật này đã phát hiện bằng chứng mới từ trầm tích được lắng đọng gần bờ biển của các đại dương cổ đại - vi cổ thực vật và các mảnh hiển vi của động vật nhỏ ... Những hóa thạch mới được phát hiện này không chỉ cho thấy sự tồn tại của những sinh vật chưa từng được biết, mà còn cũng đẩy lùi ngày tháng cho cuộc xâm chiếm đất đai của các sinh vật đa bào.

Như vậy có thể suy ra rằng hóa thạch mới được phát hiện cổ đại hơn những hóa thạch khổng lồ nhiều. Phương án C. They are older than the mega fossils = Chúng lâu đời hơn các hóa thạch khổng lồ.

A. They have not been helpful in understanding the evolution of terrestrial life = Chúng đã không hữu ích trong việc tìm hiểu sự tiến hóa của sự sống trên cạn.

B. They were found in approximately the same numbers as vascular plant fossils = Chúng được tìm thấy trong số lượng xấp xỉ như hóa thạch thực vật có mạch.

D. They consist of modern life-forms = Chúng bao gồm các hình thái sự sống hiện đại.
