Could someone try this physics question as every solution found os far has proven to be incorrect?

Many caterpillars construct cocoons from silk, one of the strongest naturally occurring materials known. Each thread is typically 2.0 ฮผm in diameter, and the silk has a Young's modulus of 4.0ร—10^9 N/m2.

Assuming that there is no appreciable space between the parallel strands, how many strands ๐‘ would be needed to make a rope 8.8 m long that would stretch only 1.02 cm when supporting a pair of 83-kg mountain climbers?
๐‘= 5.59ร—10^7strands
Again assuming that there is no appreciable space between the parallel strands, what would be the diameter ๐‘‘ of the rope?
๐‘‘= 1.495 cm
