- A simple way to disprove this hypothesis (the Innateness Hypothesis) is to demonstrate that other species have the capacity to speak but for some reason simply have not developed speech.
- A logical candidate for such a species is the chimpanzee, which shares 98.4% of the human genetic code.
- Chimpanzees cannot speak because, unlike homo sapiens, their vocal cords are located higher in their throats and cannot be controlled as delicately as human vocal cords.
- It does not follow from their lack of speech, however, that chimpanzees are incapable of language.
- Perhaps they can acquire grammar like humans if they could only express it some other way.

## Answer

1. A simple way to disprove this hypothesis (the Innateness Hypothesis) is to demonstrate that other species have the capacity to speak but for some reason simply have not developed speech.
2. A logical candidate for such a species is the chimpanzee, which shares 98.4% of the human genetic code.
3. Chimpanzees cannot speak because, unlike homo sapiens, their vocal cords are located higher in their throats and cannot be controlled as delicately as human vocal cords.
4. It does not follow from their lack of speech, however, that chimpanzees are incapable of language.
5. Perhaps they can acquire grammar like humans if they could only express it some other way.

## Explanation

The sequence is correct because it follows a logical flow: introducing the hypothesis, selecting a test subject, explaining physical constraints, and finally proposing alternative avenues for language acquisition.

(Sentence 1): The paragraph begins by introducing a simple way to disprove the Innateness Hypothesis--by demonstrating that other species have the capacity to speak but have not developed speech. (Sentence 2): The second sentence identifies the chimpanzee as a logical candidate for such an experiment, given its close genetic similarity to humans. (Sentence 3): The third sentence explains why chimpanzees cannot speak, due to their vocal cords being located higher in their throats and less controllable than human vocal cords. (Sentence 4): The fourth sentence clarifies that the lack of speech in chimpanzees does not necessarily mean they are incapable of language. (Sentence 5): The final sentence suggests that chimpanzees may be capable of acquiring grammar if they could express it in another way.

## Hints

- Start by identifying the sentence that introduces the main topic, then look for the sentence that introduces the specific animal subject.
- Notice how the text shifts from physical anatomy to the broader concept of language capability; use this transition to order the middle segments.
