A relation R has attributes A, B, C, D, E, F, G, H, I, J, and satisfies the following FDs: ABD -> EAB  -> GB   -> FC   -> JCJ  -> IG   -> H Please find the candidate key. Please provide the key; no need to show any steps. [Hint: it is a four-letter key like ABJC or EHGF, so do not waste your time computing closure of A, B, then AB, AC, and then ABC BCA, etc. Go directly to four-letter’s closures]

1. Pick your favorite piece of art that we have studied this semester. Your chosen piece cannot be one that has been discussed in the exam so far, nor one that you have already used as an answer. Include the artist, title, and date, and the lecture title where each piece was discussed. 2. Which time period, art movement, or culture is your chosen piece associated with? 3. Define the artistic style that is typically associated with that time period, art movement, or culture. What type of art do we normally see in this era or culture? 4. Does your chosen piece align with the type of art seen in this era or culture, or does it stick out as different? Why? 5. Explain why you like this piece or feel a connection to the work. 100 words minimum

Only for question 4, you are allowed to use paper submission. Please draw the diagram(s) on paper and email them to me within 10 minutes of your submission of the final exam on Canvas. Please remember that any paper emailed to me more than 10 minutes after the final exam submission on Canvas will not be considered for grading.  Additionally, please ensure your handwriting is legible. Alongside the answer to question 4, please email me any scratch paper(s) that you have used during the exam.   For all the questions, try to explain the intermediate steps. Providing the answer will only earn you 1 point for the question. Also, even if you do not get the final answer right, showing me the steps will help you to get partial credits, which is more than 1 point. Also, please take your time in answering the questions. Please do not rush and read them carefully.  

Marjorie, a retired teacher, was close to her grandchildren, Eli and Jackson, whom she helped raise after their parents passed away. In 2018, Marjorie drafted a will leaving “all my personal property to Eli and my real property to Jackson.” Marjorie also named her close friend, Simon, as executor. The will did not include a residuary clause. Marjorie signed the will in front of Simon and another friend, Fred, but did not date it. Simon and Fred both signed the will as witnesses. In 2021, after a serious argument with Jackson about selling the family cabin, Marjorie handwrote a short note that said: “I want Eli to have the cabin now because Jackson doesn’t appreciate the family history of the cabin.” Marjorie signed and dated the note and placed it into her recipe book. Marjorie told Eli to “keep this safe.” The note did not mention any other property. A week before Marjorie died in 2024, Marjorie had secretly sold the cabin and used the money to buy stocks in ABC Company. It was stipulated that Marjorie had full mental capacity during her lifetime. What are the respective interests of Eli and Jackson in Marjorie’s estate? Answer according to California law only.

In 2005, T types and signs a will that gives his sailboat to his sons, 50% of the rest of his property to his wife, and the other 50% to his two children. His wife is one witness, and one of his sons is the other. In 2010, while out to eat as a guest of his sons, T writes on a napkin, “When I die, I give 40% of my property to my wife, and 60% to my sons. Signed, Dad.” In 2012, one of T’s sons dies in a sailing accident, leaving a young child. T sells the sailboat for $100k, gives half the proceeds to his remaining son, and puts the other half in an account in his own name. He tells his wife and remaining son that the money in that account is for his grandchild. He also executes a codicil that gives 75% of his property to his wife, and 25% of his property to his living son. In 2020, when T dies, he is survived by his wife, a son, and a grandchild by his deceased son. Does T have a valid will at his death? If T has a valid will, who takes what at his death? If T’s 2012 codicil is found to be invalid, who takes what at his death? Answer according to California law.

Which of the following would not be a suitable answer to fill in the blanks of this phrase: Wnt is to Frizzled as ____________ is to ____________?

An axolotl limb with hypothetical positional information values 1 to 5 as shown above, is amputated at positional value 2. The blastema that forms is remoed and replaced with a regeneration blastema of value 4 from a donor albino (white) axolotl.  Explain what happens as this limb regenerates. Your answer should indicate the order of positional values of the resulting limb and the origin(s) of new cells (e.g. Host (pink) vs Donor (white).

Bonus question 2 * Ref: Google’s Nano banana Pro   Assume a counterfactual framework. A student plans to start a new business developing AI-enabled smart glasses designed to assist drivers. The glasses provide real-time AI voice support, including navigation assistance, weather alerts, and warnings about potential driving hazards. The student seeks to evaluate the effect of using AI glasses on driving safety. Conducting controlled experiments with drivers is infeasible due to budget limitations and ethical concerns. Instead, the student assembles observational panel data from multiple U.S. states. Some states permit the use of AI glasses while driving, whereas others prohibit it. The dataset spans periods before and after the legalization of AI glasses in each state. The student compares changes in driving safety outcomes across states over time, implicitly constructing counterfactual outcomes for treated states using untreated states as a comparison group. To estimate the effect of AI glasses on driving safety, the student should use(1) ____________________ (A. causal inference or B. prediction). The experimental design described above is best characterized as a(2)____________________ (A. randomized controlled trial or B. quasi-experiment). After completing the analysis, the student finds evidence that the use of AI glasses improves driving safety in the observed sample. Building on this result, the student plans to enhance the product by adding a new AI feature that forecasts the real-time probability of a traffic accident. If the forecasted probability exceeds a predefined threshold, the glasses issue an immediate warning to the driver. This new feature is based on(3)____________________ (A. causal inference or B. prediction). Overall, because the study relies on real-world data and counterfactual reasoning rather than abstract theoretical modeling, this project is an example of a(4)____________________ (A. empirical or B. theoretical) study.
