  1. A. 1
  2. B. 2
  3. C. 3
  4. D. 4 ✓
  5. E. 5
Explanation: The methods are deposit, withdraw , and getBalance , all inherited from the BankAccount class, plus addInterest , which was defined just for the class SavingsAccount .

The student wants to suggest a reason why the Rice’s whale is quite difficult to observe. Which choice most effectively uses relevant information from the notes to accomplish this goal?
  1. A. With so few of the Rice’s whales left in the wild, whale spotting opportunities are quite rare. ✓
  2. B. The Rice’s whale is unsurprisingly named for the man who discovered it—Dale Rice.
  3. C. The geographic vicinity in which the Rice’s whale is found is yet to be established.
  4. D. A potential oil spill poses a major threat to the long-term viability of the Rice’s whale.
Explanation: If there are few of the Rice’s whales left, it makes sense that there are fewer opportunities to observe them—thus, choice (A) is the most logical answer. Choice (B) does not have to do with the observability of the whale. Choice (C) is not supported by the notes since the whale is found in the Gulf of Mexico. Choice (D) refers to a potential future event, not to something that presents an issue for observation in the present moment.

Why are the metabolic rates of smaller organisms generally higher than those of larger organisms?
  1. A. Smaller organisms have shorter life spans and therefore must accomplish more activities in less time. This requires a faster metabolic rate.
  2. B. Smaller organisms have a higher surface area to volume ratio than larger organisms and lose more heat to the environment. ✓
  3. C. Smaller organisms are more likely to be ectothermic than larger organisms and therefore need a higher metabolic rate to compensate for this.
  4. D. Smaller organisms consume less food per gram of body weight than larger organisms and therefore need a higher metabolic rate to compensate for this.
Explanation: Smaller organisms possess a higher surface area-to-volume ratio compared to larger ones, causing them to lose body heat to the environment much faster. To maintain a stable internal temperature (homeostasis), they must generate heat at a rapid rate through cellular respiration, resulting in a higher metabolic rate per unit of mass. This physical constraint regarding heat loss is the primary driver for the difference in metabolic rates between small and large organisms.

Which choice completes the text with the most logical transition? In the past few years, more than one horribly botched painting has made the news when it was delivered back to the owner looking nothing like the original. ___________ the art restorer working on the painting is not both topnotch and very well trained in artistic techniques from the time-period of the piece, the results of a restoration attempt can be disastrous.
  1. A. However,
  2. B. In addition,
  3. C. For instance, ✓
  4. D. Surprisingly,
Explanation: The sentence following the blank provides a specific example of a cause for disastrous restoration results, which illustrates the general problem mentioned in the first sentence; therefore, "For instance" correctly signals this relationship. Choices like "However" or "Surprisingly" are incorrect because they imply a contrast or unexpected element that does not exist here, while "In addition" fails to show that the second sentence is an example rather than just another point.

Which of the following statements is the most logical prediction regarding the addition of a catalyst to this reaction? Questions 233 and 234 refer to the data below.
  1. A. The activated complex would form in less than 40 seconds.
  2. B. The enthalpy change would be lower, increasing the reaction rate.
  3. C. More reactions would occur per second. ✓
  4. D. The equilibrium would shift to favor the products.
Explanation: Reaction rateis measured by product formation (or substrate consumption) over time andis a function of the number of effective collisions that occur in a given period of time.For some reactions, the actual time course for the molecular events of the reaction is known. But in the absence of specific data, whether each individual reaction occurs faster (choice A) or more successful reactions happen per second but each reaction takes the same amount of time isn’t known. In other words, unless additional data regarding the reactionmechanism are provided, there is no way to know if the addition of the catalyst speeds up each individual reaction to occur in less than 50 seconds or if more reactants are turned into product in that time, with each reaction occurring in about 50 seconds.

In the figure below, if AB = 27, CD = 20, and the area of triangle ADC = 240, what is the area of polygon ABCD?
  1. A. 420
  2. B. 480
  3. C. 540
  4. D. 564 ✓
  5. E. 1,128
Explanation: Start with Step 1: Know the question. Underline what is the area of polygon ABCD? This polygon is not a conventional figure, but if we had to choose one figure that the polygon resembled, we might pick a rectangle. Try drawing a line at a right angle from the line segment AB so that it touches point C, thus creating a rectangle. It should look like the following: The area of polygon ABCD is equal to the area of the rectangle you've just formed, plus a little bit at the top. The question tells you that the area of triangle ADC is 240. What is the area of the rectangle you just created? If you said 480, you are exactly right, whether you knew the geometric rules that applied or whether you just measured it with your eyes. So the area of the rectangle is 480. Roughly speaking, then, what should the area of the polygon be? A little more. Let's look at the answer choices. Choices (F) and (G) are either less than or equal to 480; get rid of them. Choices (H) and (J) both seem possible; they are both a little more than 480; let's hold on to them. Choice (K) seems pretty unrealistic. We want more than 480, but 1,128 is ridiculous.

💡 Study Tips

📖 Build a study schedule and stick to it

Consistent daily study sessions of 30-60 minutes are more effective than occasional 4-hour marathons. Block specific times on your calendar and treat them like appointments you can't cancel.

📖 Test yourself before you feel ready

Retrieval practice — actively trying to recall information without looking at your notes — is one of the most effective study techniques. Even getting answers wrong strengthens your memory more than re-reading.
