Question 1
Score: 0/0

Passage: New volcanic islands begin as bare rock with almost no soil. Wind-blown dust, bird droppings, and the decay of pioneer plants gradually create thin soil layers. As soil deepens, grasses and shrubs can replace the earliest lichens and mosses. This process, called ecological succession, may take centuries, and storms can interrupt it by stripping young soils away. Why does the author mention storms?

1Passage: In coastal wetlands, grasses and reeds slow incoming water, causing suspended sediment to settle around plant roots. This gradual buildup can raise the marsh surface and help it keep pace with moderate sea-level rise. When storms remove vegetation or when seawalls block sediment from reaching the marsh, however, the system loses part of its natural repair mechanism. Which choice best states the passage's central idea?
A.Wetland plants and sediment can help marshes rebuild, but storms and barriers can disrupt that process.
B.Sea-level rise is caused mainly by reeds and other wetland plants trapping too much sediment.
C.Coastal wetlands survive only when storms remove old vegetation from the marsh surface.
D.Seawalls improve marsh health by increasing the amount of sediment that reaches plant roots.
Explanation: The passage explains a natural rebuilding process in wetlands and then names conditions that weaken it.
2Passage: In coastal wetlands, grasses and reeds slow incoming water, causing suspended sediment to settle around plant roots. This gradual buildup can raise the marsh surface and help it keep pace with moderate sea-level rise. When storms remove vegetation or when seawalls block sediment from reaching the marsh, however, the system loses part of its natural repair mechanism. According to the passage, why does sediment settle near plant roots?
A.The roots release minerals that dissolve seawalls.
B.Storms push sediment into deep offshore channels.
C.Wetland plants slow the movement of incoming water.
D.Sea-level rise turns plant roots into hard rock.
Explanation: The first sentence states that grasses and reeds slow incoming water, which causes suspended sediment to settle around their roots.
3Passage: In coastal wetlands, grasses and reeds slow incoming water, causing suspended sediment to settle around plant roots. This gradual buildup can raise the marsh surface and help it keep pace with moderate sea-level rise. When storms remove vegetation or when seawalls block sediment from reaching the marsh, however, the system loses part of its natural repair mechanism. What can be inferred about wetlands cut off from sediment by seawalls?
A.They will become deeper because plant roots produce unlimited sediment.
B.They may have more difficulty maintaining their surface elevation.
C.They will no longer be affected by storms or rising sea levels.
D.They are likely to turn into freshwater forests immediately.
Explanation: If sediment buildup helps raise the marsh surface, then blocking sediment makes that elevation-building process harder.
4Passage: In coastal wetlands, grasses and reeds slow incoming water, causing suspended sediment to settle around plant roots. This gradual buildup can raise the marsh surface and help it keep pace with moderate sea-level rise. When storms remove vegetation or when seawalls block sediment from reaching the marsh, however, the system loses part of its natural repair mechanism. In the passage, the word suspended most nearly means:
A.carried within the water
B.officially forbidden
C.emotionally uncertain
D.permanently hardened
Explanation: Sediment that settles when water slows must have been carried in the moving water, so suspended means held or carried within it.
5Passage: In coastal wetlands, grasses and reeds slow incoming water, causing suspended sediment to settle around plant roots. This gradual buildup can raise the marsh surface and help it keep pace with moderate sea-level rise. When storms remove vegetation or when seawalls block sediment from reaching the marsh, however, the system loses part of its natural repair mechanism. The phrase this gradual buildup refers to:
A.the construction of seawalls along the coast
B.the increase in storm intensity over time
C.the disappearance of marsh vegetation
D.the accumulation of sediment around plant roots
Explanation: The phrase points back to the sediment settling around plant roots in the previous sentence.
6Passage sentence: When storms remove vegetation or when seawalls block sediment from reaching the marsh, however, the system loses part of its natural repair mechanism. Which option best expresses the essential meaning of the sentence?
A.Marshes repair storms by building seawalls that keep sediment away from plants.
B.Storm damage and blocked sediment can weaken a marsh's ability to rebuild itself.
C.Wetlands lose all natural features whenever vegetation grows too quickly.
D.Seawalls and storms are useful because they speed up sediment delivery to marshes.
Explanation: The sentence says two disruptions, vegetation loss and blocked sediment, reduce the marsh's natural repair process.
7Passage: In coastal wetlands, grasses and reeds slow incoming water, causing suspended sediment to settle around plant roots. This gradual buildup can raise the marsh surface and help it keep pace with moderate sea-level rise. When storms remove vegetation or when seawalls block sediment from reaching the marsh, however, the system loses part of its natural repair mechanism. Why does the author mention seawalls?
A.To identify a human-made structure that can interrupt sediment flow
B.To show that all coastal engineering increases wetland growth
C.To define the difference between reeds and grasses
D.To prove that storms have no effect on wetland vegetation
Explanation: Seawalls are given as an example of something that blocks sediment and weakens the marsh's repair mechanism.
8Passage: [A] In coastal wetlands, grasses and reeds slow incoming water, causing suspended sediment to settle around plant roots. [B] This gradual buildup can raise the marsh surface and help it keep pace with moderate sea-level rise. [C] When storms remove vegetation or when seawalls block sediment from reaching the marsh, however, the system loses part of its natural repair mechanism. [D] Where should the sentence be inserted? Sentence: Healthy vegetation is therefore not just a surface feature but part of the wetland's engineering.
A.Position A
B.Position B
C.Position C
D.Position D
Explanation: The sentence draws a conclusion from the first two sentences about vegetation's role, so it fits after the buildup process and before the contrast introduced by however.
9Passage: In coastal wetlands, grasses and reeds slow incoming water, causing suspended sediment to settle around plant roots. This gradual buildup can raise the marsh surface and help it keep pace with moderate sea-level rise. When storms remove vegetation or when seawalls block sediment from reaching the marsh, however, the system loses part of its natural repair mechanism. Which choice provides the best prose summary of the passage?
A.Wetlands are permanent landforms because storms always add enough sediment to their surfaces.
B.Plants in wetlands trap sediment that can raise marsh surfaces, but damage to plants or sediment supply can reduce this adaptive capacity.
C.Seawalls are the main reason coastal wetlands can keep pace with moderate sea-level rise.
D.The passage explains how freshwater plants replace saltwater plants after every coastal storm.
Explanation: The best summary includes both the helpful plant-sediment process and the disruptions that can weaken it.
10Passage: In coastal wetlands, grasses and reeds slow incoming water, causing suspended sediment to settle around plant roots. This gradual buildup can raise the marsh surface and help it keep pace with moderate sea-level rise. When storms remove vegetation or when seawalls block sediment from reaching the marsh, however, the system loses part of its natural repair mechanism. A study table has the heading Factors that weaken marsh rebuilding. Which entry belongs under that heading?
A.Grasses slow incoming water near their roots.
B.Sediment settles when water movement decreases.
C.Marsh surfaces can rise through gradual buildup.
D.Seawalls block sediment from reaching the marsh.
Explanation: Blocking sediment is listed as a condition that causes the system to lose part of its natural repair mechanism.
