[Q]: A mid-1950s construction worker involved in the demolition of the "J. C. Wilber Building" finds a box inside a cornerstone. He opens it to find a commemorative document dated April 16, 1892. Inside is also a singing, dancing frog, complete with top hat and cane. After the frog suddenly performs a musical number there on the spot, the man tries exploiting the frog's talents for money. However, the frog refuses to perform for any individual other than its owner, instead devolving into croaking in the presence of others. The man frantically tries to demonstrate the frog's abilities to the outside world, first by trying to get a talent agent to accept him, then by renting out a theater for it to perform in, all to no avail.After these failed attempts to profit from the frog, the man becomes destitute and is living on a park bench, where the frog still performs only for him. A policeman overhears this and approaches the man for disturbing the peace, but when the man points out the frog as having done the singing, the officer takes the man into custody. He is committed to a psychiatric hospital along with the frog, who continues serenading the hapless patient. Following his release, the haggard, broken man, carrying the frog inside the box, spies the construction site where he originally found the box, and dumps it into the cornerstone of the future "Tregoweth Brown Building" before sneaking away. The timeline then jumps to 2056 (101 years after the cartoon's debut). The Brown Building is being demolished using futuristic ray guns, and the box with the frog is discovered yet again by a 21st-century demolition man, who, after envisioning riches as well, absconds with the frog to start the process once again., Question: What two things does the construction worker find inside the box from the cornerstone of the demolished J.C. Wilber building?
[A]: Answer: A document and a frog

He remarries Lady Tremaine, a widow with two daughters of her own, Drizella and Anastasia. After Cinderella's father dies unexpectedly, Lady Tremaine is revealed to be a cruel and selfish woman, only interested in her daughters. Cinderella is mistreated by her stepfamily, who take over the estate and ultimately reduce her to being a scullery maid in her own home. Despite this, Cinderella grows into a kind and gentle young woman, befriending the mice and birds who live around the chateau.One day, at the royal palace, the King discusses with the Grand Duke his desire for his son the Prince to settle down and have children. They organize a ball in an effort to find a suitable wife for the Prince. Cinderella asks her stepmother if she can attend, as the invitation says "every eligible maiden" is to attend. Lady Tremaine agrees, provided if Cinderella finishes her chores and find a nice dress to wear. However, the extra chores are preventing Cinderella from designing her dress on time. Cinderella's animal friends, led by Jaq, Gus and the other mice, fix up a gown that belonged to Cinderella's mother using beads and a sash thrown out by Drizella and Anastasia, respectively. When Cinderella comes down wearing her new dress, Lady Tremaine compliments the gown, pointing out the beads and the sash.
