When they reached out the opulent port the Sailors saw

Hey! You probably came from the worksheet that asks you to complete the sentence in a way that shows you understand the italicized word. The word that was italicized in this sentence was opulent so I'll tell you what it means to help you out! Opulent's definition is 'rich, luxurious and lavish'. That kind of thing. So you can finish the sentence by describing the port's expensive items and how it was clearly for rich people by the way it was decorated with jewels, gold, etc. I hope this helped you in some way or another :)

closer examination, however, finds the mcdonald's kind of job highly uneducational in several ways. far from providing opportunities for entrepreneurship (the lemonade stand) or self- discipline, self-supervision, and self-scheduling (the paper route), most teen jobs these days are highly structured — what social scientists call “highly routinized.”  

true, you still have to have the gumption to get yourself over to the hamburger stand, but once you don the prescribed uniform, your task is spelled out in minute detail.  

the dictionary definition of ubiquitous is "present, appearing, or found everywhere".
