A few years ago scientists a three-foot skeleton of an early human species on an Indonesian island. They nicknamed the a "hobbit." But the find left scientists with two major questions: Do these short, 18,000-year-old bones represent an entirely new human species? Or is it just someone with a growth disorder? Now the wrist bones may provide an answer. Researchers from the Smithsonian Institution an article in the latest issue of Science. They showed that the hobbit's wrists are different from both early humans and from Neanderthals. In fact, the wrists are closer to those of African apes. Wrist bones take in early pregnancy and don't change much. They're also particularly distinctive between species. Scientists believe this shows that an early species in the human line migrated from Africa to Asia. They evolved into a new species on the Indonesian island. If modern humans and Neanderthals have a common ancestor, then modern humans and hobbits have a common, well, grand-ancestor. Making us and hobbits kind of second cousins.

Result:

A.I. Explanation:

Correct answer: discovered
Explanation: The word 'discovered' fits grammatically as it is the past tense of the verb, aligning with the time frame indicated by 'a few years ago.' It also contextually matches the action of finding something previously unknown, which is appropriate for the skeleton of an early human species.
Meaning: 'Discovered' means to find something that was not known before, often used in the context of scientific findings.
Wrong options:
designed: 'Designed' implies creating something with a specific purpose, which does not fit the context of finding a skeleton.
invented: 'Invented' suggests creating something new that did not exist before, which is not applicable to the discovery of a skeleton.
imagined: 'Imagined' refers to forming a mental image or concept, which does not relate to the factual finding of a skeleton.
Correct answer: creature
Explanation: The term 'creature' is appropriate as it refers to a living being, which aligns with the context of a skeleton of an early human species. It fits grammatically and contextually as it describes the skeleton that was found.
Meaning: 'Creature' means a living being, especially one that is not human, which is fitting for the context of an early human species.
Wrong options:
statue: 'Statue' refers to a carved or cast figure of a person or animal, which does not apply to a skeleton.
device: 'Device' implies a mechanical or electronic tool, which is irrelevant in this biological context.
structure: 'Structure' refers to something built or constructed, which does not accurately describe a skeleton.
Correct answer: published
Explanation: The word 'published' is the correct choice as it indicates that researchers made their findings available to the public through an article, fitting grammatically in the past tense and contextually in the academic setting.
Meaning: 'Published' means to make content available to the public, typically through print or online media, especially in academic contexts.
Wrong options:
edited: 'Edited' suggests modifying content, which does not fit the context of making new findings public.
submitted: 'Submitted' implies that something was sent for consideration, which does not convey the action of making findings public.
coined: 'Coined' means to create a new term or phrase, which is not relevant to the act of sharing research findings.
Correct answer: significantly
Explanation: The adverb 'significantly' fits well as it indicates a notable difference, aligning with the context of comparing the hobbit's wrists to those of other species. It is grammatically correct and enhances the meaning of the sentence.
Meaning: 'Significantly' means in a way that is important or noticeable, emphasizing the degree of difference in the wrist structure.
Wrong options:
indistinguishably: 'Indistinguishably' suggests that the differences cannot be seen, which contradicts the context of showing differences.
cynically: 'Cynically' implies a distrustful attitude, which does not relate to the scientific context of the findings.
inextricably: 'Inextricably' means in a way that is impossible to separate, which does not fit the context of discussing differences.
Correct answer: shape
Explanation: The noun 'shape' is appropriate as it refers to the form or structure of the wrist bones, fitting grammatically and contextually in the sentence about their development during early pregnancy.
Meaning: 'Shape' refers to the external form or appearance of something, which is relevant to the discussion of wrist bones.
Wrong options:
appearance: 'Appearance' refers to the way something looks, which is less specific than 'shape' in this context.
possess: 'Possess' means to have or own, which does not fit grammatically or contextually in this sentence.
advantage: 'Advantage' refers to a beneficial factor, which is unrelated to the context of physical development.
