True! Hearing is something that is done without you realizing it. It is a natural sense that humans have. But listening requires focus and attention. You can be hearing what your teacher is saying, but not really understanding and listening to the words. Listening means you are collecting the information, and you should be able to remember it later. :)

You have done well here.  Subjective is based on or influenced by personal feelings, tastes, and opinions.   Answer D refers to insights and impulses that are unique to each person, making it personal.  In #2, wording in the sentence such as joyfulling, sunny, and kicking up their heels are all positive words.  Answer choices A, C, and D are all negative wording.  B is the correct choice.  Great job!
