❌ A. Orca diving ✅ B. The code will not compile because of line 2 ❌ C. The code will not compile because of line 8 ❌ D. The code will not compile because of line 9 ❌ E. The output cannot be determined from the code provided
Explanation: This may look like a complex question, but it is actually quite easy. Line 2 contains an invalid definition of an abstract method. Abstract methods cannot contain a body, so the code will not compile and option B is the correct answer. If the body {} was removed from line 2, the code would still not compile, although it would be line 8 that would throw the compilation error. Since dive() in Whale is abstract and Orca extends Whale, then it must implement an overridden version of dive(). The method on line 9 is an overloaded version of dive(), not an overridden version, so Orca is an invalid subclass and will not compile.

If riding a bucking bronco is your idea of fun, you’re going to love what the stock market has in store. Consider this past week’s ride a preview.The week’s action didn’t look like much, if you didn’t know better. The Dow Jones Industrial Average rose 213.12 points or 0.6%, while the S&P 500 advanced 0.5%, and the Nasdaq Composite ended little changed.
Should You Buy Bitcoin?
In general, many financial experts support their clients’ desire to buy cryptocurrency, but they don’t recommend it unless clients express interest. “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college,” says Ian Harvey, a certified financial planner (CFP) in New York City. “Then it wasn’t worth the risk.” The speculative nature of cryptocurrency leads some planners to recommend it for clients’ “side” investments. “Some call it a Vegas account,” says Scott Hammel, a CFP in Dallas. “Let’s keep this away from our real long-term perspective, make sure it doesn’t become too large a portion of your portfolio.” In a very real sense, Bitcoin is like a single stock, and advisors wouldn’t recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if you’re passionate about it. “If it was one stock, you would never allocate any significant portion of your portfolio to it,” Hammel says.
