SAT Rhetorical Synthesis Practice — Drill 5

The student wants to contrast cryopreservation with standard refrigeration. Which choice most effectively uses relevant information from the notes to accomplish this goal?

1. A The technique is currently used to preserve reproductive cells, blood samples, and some research tissue samples.
2. B Preservation techniques have advanced rapidly over the past several decades.
3. C Cryopreserved tissue must be cooled at a carefully controlled rate to prevent ice crystal damage.
4. D Unlike standard refrigeration, which only slows cellular processes and decay, cryopreservation uses extremely low temperatures to stop these processes for future use.

The student wants to explain the underlying mechanism that causes a sinkhole to form. Which choice most effectively uses relevant information from the notes to accomplish this goal?

1. A Prolonged drought followed by heavy rainfall is a common trigger for sudden sinkhole collapse.
2. B Sinkholes form when underground water dissolves soluble rock like limestone, creating a hidden void that causes the surface above to eventually collapse.
3. C Florida experiences a high number of sinkholes due to its widespread limestone bedrock.
4. D Florida is home to a number of well-known geological features.

The student wants to explain the underlying process that creates karst landscapes. Which choice most effectively uses relevant information from the notes to accomplish this goal?

1. A Karst regions often have unusually vulnerable groundwater systems due to limited natural filtering.
2. B Surface features of karst landscapes include sinkholes, disappearing streams, and natural bridges.
3. C Karst landscapes form over thousands of years as slightly acidic rainwater gradually dissolves soluble bedrock like limestone, creating underground caves and channels.
4. D Karst landscapes form in regions with soluble bedrock, primarily limestone, gypsum, or dolomite.

The student wants to explain how Spencer discovered the principle behind the microwave oven. Which choice most effectively uses relevant information from the notes to accomplish this goal?

1. A Spencer experimented further by popping popcorn and exploding an egg using the same equipment.
2. B The first commercial microwave oven, released in 1947, was nearly six feet tall.
3. C Spencer noticed that a candy bar in his pocket had melted while he stood near an active magnetron during radar equipment testing, leading him to investigate further.
4. D The microwave oven was accidentally discovered in 1945 by engineer Percy Spencer.

The student wants to contrast CRISPR with earlier gene-editing methods. Which choice most effectively uses relevant information from the notes to accomplish this goal?

1. A CRISPR-Cas9, adapted from a bacterial immune defense system, has transformed the field of genetics.
2. B Unlike earlier gene-editing techniques, which were far less precise and much more expensive, CRISPR-Cas9 allows scientists to cut DNA at precise locations.
3. C CRISPR-Cas9 has been used to develop potential treatments for sickle cell disease.
4. D Gene-editing technology has advanced rapidly over the past several decades.

The student wants to explain the basic mechanism by which a pressure cooker reduces cooking time. Which choice most effectively uses relevant information from the notes to accomplish this goal?

1. A Early pressure cookers were prone to dangerous explosions due to inconsistent pressure-release mechanisms.
2. B Modern pressure cookers include multiple safety valves that make them safer than earlier designs.
3. C By trapping steam to raise the boiling point of water inside a sealed pot, a pressure cooker allows food to cook at higher temperatures, reducing cooking time.
4. D The pressure cooker was patented in the 17th century by Denis Papin.

The student wants to summarize a surprising finding of the pilot program. Which choice most effectively uses relevant information from the notes to accomplish this goal?

1. A A pilot program offered free public transit passes to residents of a mid-sized city for one year.
2. B Overall car traffic in the city center decreased by 8% during the pilot.
3. C Although the program aimed broadly to shift residents away from cars, ridership increased mainly among residents who did not previously own a car, with little change among existing car owners.
4. D Public transit policy has been debated by urban planners for decades.

The student wants to support the claim that Lovelace is considered the first computer programmer. Which choice most effectively uses relevant information from the notes to accomplish this goal?

1. A Lovelace is often credited as the first computer programmer because she wrote what is now considered the first algorithm intended to be processed by a machine.
2. B Ada Lovelace worked closely with Charles Babbage on his proposed Analytical Engine during the 1840s.
3. C Charles Babbage proposed the Analytical Engine, an early mechanical general-purpose computer, in the 1840s.
4. D Lovelace's notes on the Analytical Engine were three times longer than Babbage's original paper on the subject.

The student wants to emphasize why the axolotl is of interest to medical researchers. Which choice most effectively uses relevant information from the notes to accomplish this goal?

1. A The axolotl, a salamander native to lakes near Mexico City, never undergoes metamorphosis.
2. B Native to lakes near Mexico City, the axolotl is a distinctive type of salamander.
3. C Because the axolotl can regenerate limbs, spinal-cord tissue, and even parts of its heart, scientists study it to understand tissue regeneration in humans.
4. D The axolotl is a salamander that keeps its gills for its entire life.
