What is the author's purpose in this excerpt?

C. To show examples of reasons books have been banned

We know that the author's purpose is this option and not the others because throughout the text, they only focus on giving examples of the reasons books have been banned or challenged: People object to certain books because they introduce ideas or topics with a vulgar language, others because the ideas expressed in the book do not align with their values, or because some books introduce ideas that people find it difficult to examine or to think or to talk about.

this is the answer , p = 1 + (1/10)x

step-by-step explanation:

we have,

at sea level pressure is 1 atmosphere (i.e at x =0, p0=1 atmosphere)

at depth 23 meters , pressure = 3.3 atmosphere

since the pressure increases at constant rate as the depth increases, so we can write a relation as:

p =p0 +   kx   , where p is the pressure  , p0 is the initial pressure, x is the depth and k is constant rate of increasing.

to find constant rate k, plug p = 3.3 , p0 = 1 and x= 23 meters

we get,

  3.3 = 1 + k * 23

k = 2.3 / 23   = 1/10

so we can write the function formula as:   p = 1 + (1/10)x

i think the answer might compound
