13. Prose Summary

Q. Directions: An introductory sentence for a brief summary of the passage is provided below. Complete the summary by selecting the THREE answer choices that express the most important ideas in the passage. Some sentences do not belong in the summary because they express ideas that are not presented in the passage or are minor ideas in the passage. This question is worth 2 points.

Why? It took centuries of scientific thought and research to achieve the understanding of the cell that is shared by scientists today.

Correct Answer Choices Clues in the passage
(B) Using a newly introduced microscope to look at cork samples, Robert Hooke was able for the first time to observe the presence of cells. Clue 13(B)[lines 33-38] It was such a device that allowed English scientist Robert Hooke in 1663 to become the first known human to observe a cell. He cut some thin slivers of cork … and viewed them under the microscope.
(C) In the early 1800s, cytoplasm and nuclei were both discovered to be important components of plant cells, and the first Cell Theory was introduced. Clue 13(C)[lines 51-60] During the early part of the century,… Living plant cells, as opposed to those of Hooke’s cork samples, were found to contain a variety of smaller elements surrounded by a liquid mixture termed “cytoplasm.” In 1833, the naturalist Robert Brown discovered the nucleus, or central structure, of plant cells.

 

[lines 66-67] Schwann subsequently formulated what became known as the Cell Theory.

(E) The Cell Theory was soon revised to include new information about cellular reproduction and became the foundation of modern cellular study. Clue 13(E)[lines 79-82] Rudolf Virchow corrected this misunderstanding, asserting that cells reproduce by dividing and that they can only be created by other cells.

25. Prose Summary

Q. Directions: An introductory sentence for a brief summary of the passage is provided below. Complete the summary by selecting the THREE answer choices that express the most important ideas in the passage. Some sentences do not belong in the summary because they express ideas that are not presented in the passage or are minor ideas in the passage. This question is worth 2 points.

Why? Pollination takes place when pollen is carried from one part of a plant to another, and this process has occurred naturally for thousands of years.

 

Correct Answer Choices ; Clues in the passage
(B) Modem human practices, such as creating single-crop fields, have led to the failure of natural pollination in many cases. Clue 25(B)[lines 27-33] However, in modern U.S. food production, this method (natural pollination) alone is no longer sufficient to fertilize all the plants involved. This is because current agricultural practices often encourage the seeding of large fields with a single crop, thus reducing the diversity of the land.
(C) Farmers throughout the United States employ large concentrations of honeybees to pollinate their fields, a process known as managed pollination. Clue 25(C)[lines 54-57] “Managed pollinators” is a term ascribed to bees that are cultivated for the specific purpose of agricultural pollination.

 

[lines 66-69] Fruit and vegetable growers all over the United States contract with beekeepers, hiring the services of honeybees to pollinate their fields.

(F) Artificial pollination methods such as electrostatic pollination offer an alternative to the use of insects that are vulnerable to diseases and environmental changes. Clue 25(F)[lines 78-81] managed honeybee populations are susceptible to the same factors— such as harmful pesticides and insect diseases [lines 91-96] This method (artificial pollination) accomplishes pollination through artificial techniques, eliminating the need for natural or managed pollinators like honeybees. One such technique currently in use is called electrostatic pollination.

► The whole passage focuses on the three pollination methods and their advantages and disadvantages. And it follows that <{B) Problems in natural pollination — (C) Managed pollination, an alternative to natural pollination — (F) A new alternative, artificial pollination) See on p.297
