Which sentence is written in a style that makes it appropriate for an audience made up of highly trained auto mechanics? the engine roared to life as i turned the key, and people on the sidewalk stopped to stare at the car. my first car was red with a white racing stripe, and the chrome on its sides shined in the bright arizona sunlight. i checked the carburetor and noticed the butterfly valve was cracked, which threw off the engine's air intake. the car was in bad shape; it had two flat tires, a broken taillight, and there were dents all over its hood.

The answer is "I checked the carburetor and noticed the butterfly valve was cracked, which threw off the engine's air intake."

Explanation:

An audience made up of highly trained auto mechanics is an audience capable of understanding technical language. People in general may own a car but not necessarily know what the car parts are called and what function each of them has. So, most people would not comprehend the sentence  "I checked the carburetor and noticed the butterfly valve was cracked, which threw off the engine's air intake", but auto mechanics would. The other sentences, on the other hand, focus on simple details such as the car color, or the flat tires. They do mention a couple of car parts - taillight and hood -, but these are simple and known of the general public.

what motivates odysseus to tell a lie to the cyclops

i’m writing a memoir and i’ve been given the great suggestion of placing a ‘sub-narrative’ within some of the chapters – sort of, what was going on with me in the grand scheme of things.

i was wondering how to format this so that it is very obvious we are stepping out the of story.

firstly is a change in font from serif to sans workable? i also use dashes for a scene change. was thinking of using a different scene-changer too.

here’s a (shortened) example:

university – or what’s known as ‘uni’ in australia – were some of the best days of my life. where else do you get to potter around in a great location, have very little responsibility, learn lots of things, do lots of things and walk out four years later with a bonus – a degree!

with my university years i had immersed myself into community of intelligent ambitious people. generally everyone had a confidence about themselves. they knew where they were going in life and weren’t threatened by others.
