Direction: Each of the following items in this section consists of a sentence, the parts of which have been jumbled. These parts have been labeled. Given below each sentence are four sequences. You are required to rearrange the jumbled parts of the sentence and mark your response accordingly: humans and machines have co-existed dating back to the invention of P Q the potter's wheel in ancient Mesopotamia at the physical level for millennia R S

The sentence must be rearranged to form a grammatically coherent statement. The subject and verb are established in the first segment: 'humans and machines have co-existed'. This is followed by the prepositional phrase 'at the physical level for millennia' (S), which qualifies the nature and duration of the co-existence. The phrase 'dating back to the invention of' (P) acts as a temporal bridge leading to the specific historical event. Finally, 'the potter's wheel in ancient Mesopotamia' (R) completes the sentence by identifying the invention mentioned. Historical evidence confirms that the potter's wheel, invented in Mesopotamia around 3500 B.C., represents one of the earliest instances of human-machine interaction [1]. This sequence (Q-S-P-R) logically connects the abstract concept of co-existence to its physical origins in ancient civilization.
