The prefix "inter-" should help you to figure out this word's meaning, even if you do not know it otherwise. This prefix means between. When you go to a theatre show, there is "intermission." This is the break that is between the main acts. This prefix should not be confused with "intra-," which means within. Now, "interspersed" means scattered between. When something is sparse, it is scattered. Thus, the "-spersed" portion of the word means scattered. When you intersperse something among other things, you mix it into them. Thus, the best option for this question is "mix."

"Immoral" is made up of a root word, "moral," and a Latin prefix, "im." "Moral" means to act correctly based on concepts of right and wrong. The prefix "im" means not. Therefore, immoral means to act incorrectly. An example would be that it is immoral to steal.

The root word, "yield" means to surrender or give way. For instance, a yield sign on a road means that you must allow cars on the other road to have the right of way. The Latin prefix "un" means not. Therefore, "unyielding" means to NOT surrender. The answer, "inflexible" has another Latin prefix, "in," which means not. "Inflexible" means to NOT be flexible or to NOT give way.

The Latin prefix dis- means apart or away; in this case, dispel means to take away. For example, to "dispel" a rumor is to get rid of it or squash it through some action of proof (against it). The words "embrace," "establish," and "insert" antonyms to "dispel." The word "censor" is the forceful blocking of another person's freedom of expression or action. It is a higher degree of intensity in relation to dispel. Therefore, the best option is "eliminate." 

The Latin prefix col- means together, joint, as in "collaborate" which means to work together. So, a "collision" is a coming together, a crash, an accident. When two cars hit one another this is called a "collision." To provide additional help, "accord" means agreement, harmony. 

The Latin prefix viv- means life, live, as in "revive" which means bring back to life. So, "vivacious" means full of life, spirited, lively. To provide further help, "lifeless" means not alive, not moving; "homely" means plain, unattractive; "homeless" means without a home; "nomadic" describes someone who moves constantly and does not live in any one place.

The latin prefix cred- means believe, as in "incredible" which means not believable, too amazing to be accepted as true. So, "credence" means faith, belief, trust, confidence in something being true. Additionally, "suspicion" is a sneaking feeling that something is true; "industry" is work or business.

The Latin prefix bell- means war, as in "bellicose" which means warlike. So, "belligerent" means hostile, aggressive, desiring conflict. To provide further help, "lofty" means tall, imposing; "penniless" means very poor; "opulent" means luxurious; "passive" means not aggressive.

The Latin prefix ambul- means walk, move, as in "ambulance" a vehicle that moves a patient to the hospital. So, to "amble" means to walk slowly, to wander, to stroll. To provide additional help, "sprint" means run fast; "demean" means embarrass, humiliate; "elicit" means bring out of someone, get a response to.

The Latin prefix lun- means moon, as in "lunar cycle" which refers to the movement of the moon. So, this one is a little more difficult to decipher than usual because it relies on some interesting knowledge of the distant past. People use to believe that the moon affects people's moods (some people still believe this) and can cause conditions like insanity. So "lunacy" means madness (caused by the moon), insanity, craziness. To provide additional help, "abundance" means a large and more than adequate supply of something; "severe" means harsh or intense; "perilous" means dangerous; "youthfulness" is the quality of being young.
