Based on the evidence in this passege from to build a fire, which statement is the best example of the theme?

a.) the dog inherited knowledge of the cold.

b.) man should use imagination to survive

c.)the dog knows its too cold to be outside

d.)instinct is an important part of survival

( need answer asap)

D.) Instinct is an important part of survival

The dog represents pure instinct, a trait necessary for survival in the extremely cold Yukon at this time of year.  ("But the dog knew; all its ancestry knew, and it had inherited the knowledge. ")

The man never uses instinct, which would inform him without thinking that certain actions are dangerous while others are absolutely necessary for survival. The reason the man never uses instinct is explained in this sentence: "Possibly all the generations of his ancestry had been ignorant of cold, of real cold, of cold one hundred and seven degrees below freezing-point."

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

explanation:

b is the answer
