This sentence clearly is contrasting Regina and her sister. Regina is a careful planner who seems to set out to do exactly what she plans. From what we can tell, she does not deviate from these plans. A person who is impulsive is just the opposite of this. He or she follows his or her impulses (wishes or desires), often going from one thing to the next without much explanation. Now, this can seem to be irrational, but these two words are not quite the same. An irrational person can also be someone who just can't "think straight" because he or she is angry. An impulsive person is a closer contrast to Regina's personality.

Animals that are amphibious can inhabit land and water. Therefore the best answer choice here is amphibious.

All that we know about the statue is that it is drawing people's attention. It might have been very "expensive," or it might have been very large ("massive"); however, we just don't know those details. All that we know is that the statue seems to be very interesting. When something is "intriguing," it draws attention and interest. Among the options provided, the word "intriguing" is the only one that expresses this general idea of being interesting.

The key word in this sentence is "shock." It is stating that a suggestion that is shocking is able to make people pay attention. Now, a violent suggestion can do this, but really that is more than is being said by the sentence. The word "outrageous" is much closer to "shocking." Something that is outrageous is shockingly "over the top." It is extreme.

The important thing to note is Robert's fear. He was afraid that having many people in charge of the food would lead to the food coming up missing. (Rations can refer to the limited food that is given to people in fixed amounts. The word can also be used in the plural like this just to mean "the food that is available.") Therefore, Robert wanted to have complete control over the food. That is, he wanted exclusive control—control that excluded everyone else from making decisions.

"Lukewarm" often refers to the temperature of liquids or beverages; for instance, one might call a cup of coffee or tea that has slightly cooled off since it was prepared or served "lukewarm."

The sentence suggests that the wealthy man was loved because of his willingness to share his time and money. To be "generous" means to be giving; "generously" means kindly or liberally.

"Smoothly" and "jaggedly" are antonyms.
