According to popular wisdom, Tyrannosaurus rex were legendary hunters; indeed, evidence of their hunting prowess lingers in the form of bite marks found on the bones of various herbivorous sauropod dinosaurs, like brontosauruses. That being said, some researchers have argued that many of these bite marks are lacking certain indicators that would imply that they were the result of hunting: namely, a lack of trace evidence of healing in the bones. Though this could mean that all the injuries were incurred in a single lethal encounter, it also could indicate that post-mortem scavenging is what led to the bite marks on the bones of the herbivores. This suggests that -------What choice logically completes the text? Tyrannosaurus rex may not have been responsible for the bite marks discovered on the sauropod bones.eliminatedespite the lore around their hunting skills, Tyrannosaurus rex may have also relied on the scavenging of already deceased dinosaurs to supplement their diet. eliminateTyrannosaurus rex were more skilled at hunting than was previously believed, and killed the majority of their prey in single, lethal attacks.eliminatesauropods were frequently able to outrun predators like Tyrannosaurus rex, unless they were ill or already dying.

In the 1980s, scientists at the New Mexico Museum of Natural History acquired a partial skull from a large adult from the genus Tyrannosaurus and identified the species as Tyrannosaurus rex. In 2013, Sebastian Dalman began working on the specimen and noticed small differences between the skull found in the 80s and other T. rex skulls in the museum's collection. The jaw of the New Mexico specimen was more slender, and its teeth lacked the prominent ridge of bone found behind T. rex’s eye. This evidence allowed Dalman to theorize that -------Which choice most logically completes the text?Tyrannosaurus skulls were frequently misidentified as T. rex.eliminatethe New Mexico specimen was a million years older than the T. rex.eliminateTyrannosaurus habitat ranged from North America to Alaska and Mexico.eliminatethe New Mexico specimen was another species of Tyrannosaurus entirely

Which statement from the article best supports the idea that the Raptorex may not be an ancestor of the T. rex?A.Sereno believes that the Raptorex was a predator.B.…Drawings of what the Raptorex might have looked like show that there were differences between its appearance and that of the massive T. rex.C.It may have run down prey with its strong legs, killed with its powerful jaws, and clutched its victims with its two-fingered "hands."D.The newly found fossil looks a lot like T. rex fossils.SUBMITExtras

For many years, there was no evidence of small plant-eating dinosaurs in modern-day North Texas. In fact, dinosaur fossils from about 100 million years ago in North America have been something of a rarity, making the history of the Mesozoic Era on the continent unclear. In a discovery that both disproves the conclusion that small plant-eating dinosaurs never lived in Texas and provides clarity on this era in the area, scientists from the Perot Museum of Nature and Science discovered a jawbone fossil near Lake Grapevine, Texas and determined it belonged to a small herbivorous dinosaur.According to the text, why was the Perot Museum’s discovery of the jawbone fossil significant?The jawbone fossil constitutes the first evidence found by scientists that herbivorous dinosaurs lived more than 100 million years ago.eliminateThe jawbone fossil helps establish that plant-eating dinosaurs’ defining features were their jawbones.eliminateThe jawbone fossil helps establish a more accurate timeline of the evolution of herbivorous dinosaurs in North America.eliminateThe jawbone fossil constitutes the first evidence found by scientists that small herbivorous dinosaurs existed in North Texas and gives a clearer picture of the Mesozoic Era in North America.

While researching a topic, a student has taken thefollowing notes:• Pterosaurs were flying reptiles that existedmillions of years ago.• In a 2021 study, Anusuya Chinsamy-Turananalyzed fragments of pterosaur jawbones locatedin the Sahara Desert.• She was initially unsure if the bones belonged tojuvenile or adult pterosaurs.• She used advanced microscope techniques todetermine that the bones had few growth linesrelative to the bones of fully grown pterosaurs.• She concluded that the bones belonged tojuveniles.The student wants to present the study and itsfindings. Which choice most effectively uses relevantinformation from the notes to accomplish this goal?A) In 2021, Chinsamy-Turan studied pterosaurjawbones and was initially unsure if the bonesbelonged to juveniles or adults.B) Pterosaur jawbones located in the Sahara Desertwere the focus of a 2021 study.C) In a 2021 study, Chinsamy-Turan used advancedmicroscope techniques to analyze the jawbonesof pterosaurs, flying reptiles that existed millionsof years ago.D) In a 2021 study, Chinsamy-Turan determinedthat pterosaur jawbones located in the SaharaDesert had few growth lines relative to the bonesof fully grown pterosaurs and thus belonged tojuveniles.33While researching a topic, a student has taken thefollowing notes:• African American women played prominent rolesin the Civil Rights Movement, including at thefamous 1963 March on Washington.• Civil rights activist Anna Hedgeman, one of themarch’s organizers, was a political adviser whohad worked for President Truman.• Civil rights activist Daisy Bates was a well-knownjournalist and advocate for school desegregation.• Hedgeman worked behind the scenes to makesure a woman was included in the lineup ofspeakers at the march.• Bates was the sole woman to speak, delivering abrief but memorable address to the cheeringcrowd.The student wants to compare the two women’scontributions to the March on Washington. Whichchoice most effectively uses relevant informationfrom the notes to accomplish this goal?A) Hedgeman and Bates contributed to the marchin different ways; Bates, for example, delivered abrief but memorable address.B) Hedgeman worked in politics and helpedorganize the march, while Bates was a journalistand school desegregation advocate.C) Although Hedgeman worked behind the scenesto make sure a woman speaker was included,Bates was the sole woman to speak at the march.D) Many African American women, including Batesand Hedgeman, fought for civil rights, but onlyone spoke at the march.
