Using "Preserving Plants"
How do the photograph and caption after paragraph 4 help the reader better understand the selection?
They explain how endophytes work to help plants.
They demonstrate the effect endophytes can have on plants.
They illustrate what kinds of plants endophytes can help.
They show the conditions against which endophytes can protect plants.
Using "Preserving Plants"
What is paragraph 1 mostly about?
The unusual conditions in which some plants can survive
The occurrence of geothermal vents in several western states
The way geothermal vents release pressure in the form of steam
The types of plants that microbiologists have observed at a national park
Using "Preserving Plants"
An idea emphasized throughout the selection is that Rodriguez’s endophyte solution —
can improve plant life in national parks
eliminates the need to water plants regularly
will allow farmers to plant crops regardless of the season
can restore a plant’s natural resistance to the effects of a harsh climate
Use "The Cure for Concrete"
Which statement best expresses the main idea of paragraph 3?
Modern highways and bridges are often constructed with concrete.
Concrete was used by ancient Romans to build massive structures.
The demand for concrete has doubled in the last decade.
Concrete has been and continues to be an important building material.
Using "The Cure for Concrete"
How does the author organize paragraph 1?
By listing types of bacteria and then telling how they help fight diseases in the human body
By defining bacteria and then explaining how bacteria are used in some products
By stating a popular belief about bacteria and then disproving it with examples
By comparing good and bad bacteria and then describing how bacteria work
Using "Preserving Plants"
What is the best summary of the article?
Concrete is a popular material, but it can develop cracks over time. Microbiologist Hendrik Jonkers believes that adding bacteria to concrete can help remedy this problem and provide savings for the construction industry.
Hendrik Jonkers, a Dutch microbiologist, noticed that concrete cracks over time. He
decided to add bacteria to concrete to make a substance called bioconcrete. The bacteria
are placed inside plastic capsules that are mixed into wet concrete.
A Dutch microbiologist named Hendrik Jonkers became interested in investigating how
bacteria might be applied to concrete to fill cracks in concrete caused by water. He
developed a self-healing bioconcrete that works to make concrete more durable.
Microbiologist Hendrik Jonkers wondered if concrete could repair itself in the same way
that human bones do. He developed bioconcrete, which was used to build a lifeguard
station near a lake in the Netherlands and repair an irrigation system in Ecuador.
Use both articles.
What is one way that Rodriguez’s and Jonkers’ methods were similar?
They both created mixtures using living materials.
They both traveled to an unfamiliar location to begin their research.
They both studied particular animals to inform their research.
They both considered how temperature might affect their results.
Using both articles.
What is one problem presented about bioconcrete that is not presented about endophyte fungi?
Bioconcrete is expensive to produce.
Bioconcrete may be unintentionally destroyed.
Bioconcrete contains harmful bacteria.
Bioconcrete is exposed to weather conditions.
Use both articles.
What is one difference between Rodriguez’s endophyte mixture and the bacteria in Jonkers’ products?
The endophyte mixture is clearly visible on seeds. However, the bacteria in the concrete cannot be detected.
The endophyte mixture covers the outside of seeds. However, the bacteria are placed inside the concrete.
The endophyte mixture is not a substance found naturally in plants. However, the bacteria is a natural part of concrete.
The endophyte mixture remains inactive for a period of time. However, the bacteria begin to work immediately.
Using both articles.
Read this sentence from paragraph 5 of “Persevering Plants.”
Rodriguez has tested his endophyte mixture on
crops and achieved success.
Which sentence from “The Cure for Concrete” shows a similar outcome for bioconcrete?
The bacteria can live in the hardened concrete for decades. (paragraph 5)
In 2011 self-healing concrete was used to construct a lifeguard station near a lake in the
Netherlands. (paragraph 6)
With the help of Jonkers’ bioconcrete, the lifeguard station has remained intact.
(paragraph 6)
Bioconcrete has been used on the floors and roofs of parking garages. (paragraph 6)
