While researching a topic, a student has taken the following notes: In 2023, anthropologists at NYU discovered a site at Lake Victoria in Kenya that dates to 2.9 million years old The site contains several stone tools. Early hominin molars from the group Paranthropus were also found near the stone tools. Previously, it was thought that only the genus Homo, to which humans belong and arrived later than Paranthropus, produced and utilized stone tools.The student wants to present the NYU research from Kenya and its conclusions. Which choice most effectively uses relevant information from the notes to accomplish this goal? Stone tool fragments and Paranthropus molars thought to be over 2.9 million years old were found near Lake Victoria, Kenya. eliminateA 2023 excavation of a site in Kenya found stone tools which suggests that stone tools may have been made or used earlier than previously thought. eliminateIn 2023, anthropologists studied what tools early Paranthropus may have used in Kenya. eliminateAs part of a 2023 study on early hominins, stone tools were discovered in Lake Victoria, Kenya. eliminate

While researching a topic, a student has taken the following notes:Ancient wood products are rare because organic material degrades over thousands of years, which has historically made it difficult for scientists to pinpoint when prehistoric people began doing woodwork.A 2023 archaeological study found notched and tapered logs buried under sand in Zambia.Scientists also found stone tools in layers of sediment as old as 300,000 to 500,000 years old.This suggests that humans at that time engaged in woodwork.The student wants to present the 2023 study in Zambia and its conclusions. Which choice most effectively uses relevant information from the notes to accomplish this goal?As part of a 2023 study, archeologists in Zambia unearthed notched and tapered logs, alongside stone tools, believed to be between 300,000 and 500,000 years old.eliminateIn 2023, archeologists studied early humans in Zambia and what kind of tools they used.eliminateIn 2023, archeologists in Zambia found notched and tapered logs, suggesting that ancient humans engaged in woodworking as early as 500,000 years ago.eliminateThe study which found ancient tools in Zambia in 2023 is important because it helped answer a question which has eluded scientists for many years.

What do researchers know about Middle Stone Age tools in Africa (these tools were used by Homo heidelbergensis and early Homo sapiens).

When written texts are unavailable, what are the two ways archaeologists can most assign confidently approximate dates to ancient items, structures, or organic remains?Group of answer choicesApplying the concept of stratigraphy when conducting an archaeological excavationCarbon-14 (radiocarbon) datingStrontium isotope analysis of teeth and bonesStudying dental enamel hypoplasia

While researching a topic, a student has taken the following notes:Mayan tapirs (Tapirus indicus) have been bred in captivity under governmental management because they’re an endangered species. In 2020, Christina Buesching studied how social and environmental conditions influenced the reproductive behavior of Mayan tapirs. Larger enclosure sizes increased social and reproductive behaviors. She concluded that tapirs needed space to socialize and reproduce.The student wants to present the study and its findings. Which choice most effectively uses relevant information from the notes to accomplish this goal?The enclosure sizes of Mayan tapirs were the focus of a 2020 study.eliminateBecause Mayan tapirs (Tapirus indicus) are endangered and bred in captivity, Christina Buesching studied what factors encouraged them to reproduce.eliminateIn a 2020 study of tapir reproduction in captivity, Christina Buesching determined that larger enclosure size increased the possibility of tapirs reproducing. eliminateResearch suggests that Mayan tapirs are more likely to engage in reproductive behavior in larger enclosures.

While researching a topic, a student has taken the following notes: James Watson and Francis Crick proposed the double helix structure of DNA in 1953. This structure allowed for DNA to be easily copied during cell division. Watson and Crick initially thought DNA copied itself through a conservative mechanism. Their discovery revolutionized the understanding of genetics. An improved understanding of genetics has led to breakthroughs in medical treatments.27Mark for ReviewABCThe student wants to emphasize the significance of Watson and Crick's discovery.
