While preparing a presentation on urban ecology, a student takes the following notes:
* Urban coyotes (*Canis latrans*) frequently adjust their diets to survive in metropolitan environments.
* Ecologist Dr. Laura Adams conducted a five-year study analyzing the diets of urban coyotes in Chicago.
* The study revealed that human-provided food, such as garbage and pet food, made up 35% of the coyotes' diet overall.
* Adams observed that coyotes living closer to large city parks consumed significantly more rodents and fruits (60% of their diet) than did coyotes in dense commercial zones.
* The remaining portion of the coyotes' diet in both areas consisted of ornamental plants and insects.
* Adams concluded that coyote diets are heavily influenced by the specific micro-habitats available within a city.

The student wants to support the claim that the diet of Chicago's urban coyotes is shaped by the specific city zones they inhabit. Which choice most effectively uses information from the notes to accomplish this goal?

While conducting research on the architectural history of Ethiopia, a student took the following notes:

- The structure features $34$ rectangular columns that support its outer roof.
- Construction of the church is traditionally attributed to King Gebre Meskel Lalibela in the late $12\text{th}$ or early $13\text{th}$ century.

The student wants to emphasize the physical dimensions of Biete Medhane Alem. Which choice most effectively uses information from the given notes to accomplish this goal?

While researching the fossil *Tullimonstrum gregarium*, a student takes the following notes:

* *Tullimonstrum gregarium* (commonly known as the Tully monster) is an extinct, soft-bodied marine animal that lived approximately 300 million years ago.
* Since the discovery of Tully monster fossils in Illinois in 1958, its classification has been a subject of intense scientific debate.
* In 2016, Victoria McCoy and colleagues analyzed the fossils and concluded the Tully monster was a vertebrate, citing a structure they identified as a primitive backbone (notochord).
* In 2023, Shigeru Kuratani and colleagues conducted a study using advanced 3D chemical imaging to examine the fossilized tissues in detail.
* Kuratani's team determined that the disputed structure lacked the characteristics of a vertebrate notochord, concluding that the Tully monster was actually an invertebrate.

For decades, agricultural scientists assumed that the primary benefit of flooding rice paddies was to provide the crops with constant hydration. Recent field trials, ______ have shown that rice plants can grow equally well in moist but unflooded soil, suggesting that the practice of flooding is actually more useful for suppressing weeds than for watering the crops.
