Problem: Flowering plant:

In most taxonomies, the flowering plants are treated as a coherent group. The most popular descriptive name has been Angiospermae (Angiosperms), with Anthophyta ("flowering plants") a second choice. These names are not linked to any rank. The Wettstein system and the Engler system use the name Angiospermae, at the assigned rank of subdivision. The Reveal system treated flowering plants as subdivision Magnoliophytina (Frohne & U. Jensen ex Reveal, Phytologia 79: 70 1996), but later split it to Magnoliopsida, Liliopsida, and Rosopsida. The Takhtajan system and Cronquist system treat this group at the rank of division, leading to the name Magnoliophyta (from the family name Magnoliaceae). The Dahlgren system and Thorne system (1992) treat this group at the rank of class, leading to the name Magnoliopsida. The APG system of 1998, and the later 2003 and 2009 revisions, treat the flowering plants as a clade called angiosperms without a formal botanical name. However, a formal classification was published alongside the 2009 revision in which the flowering plants form the Subclass Magnoliidae.

Question: The Chicago Cubs have not won a World Series championship since 1908, and have not appeared in the Fall Classic since 1945, although between their postseason appearance in 1984 and their most recent in 2015, they have made the postseason seven times. 107 seasons is the longest championship drought in all four of the major North American professional sports leagues, which also includes the National Football League (NFL), the National Basketball Association (NBA), and the National Hockey League (NHL). In fact, the Cubs' last World Series title occurred before those other three leagues even existed, and even the Cubs' last World Series appearance predates the founding of the NBA. The much publicized drought was concurrent to championship droughts by the Boston Red Sox and the Chicago White Sox, who both had over 80 years between championships. It is this unfortunate distinction that has led to the club often being known as "The Lovable Losers." The team was one win away from breaking what is often called the "Curse of the Billy Goat" in 1984 and 2003 (Steve Bartman incident), but was unable get the victory that would send it to the World Series.
Is there an answer to this question: When was the last time the Chicago Cubs appeared in the Fall Classic?

Answer: 1945

Question: Digimon hatch from types of eggs which are called Digi-Eggs (, Dejitama?). In the English iterations of the franchise there is another type of Digi-Egg that can be used to digivolve, or transform, Digimon. This second type of Digi-Egg is called a Digimental (, Dejimentaru?) in Japanese. (This type of Digi-Egg was also featured as a major object throughout season 2 as a way of Digivolution available only to certain characters at certain points throughout the season.) They age via a process called "Digivolution" which changes their appearance and increases their powers. The effect of Digivolution, however, is not permanent in the partner Digimon of the main characters in the anime, and Digimon who have digivolved will most of the time revert to their previous form after a battle or if they are too weak to continue. Some Digimon act feral. Most, however, are capable of intelligence and human speech. They are able to digivolve by the use of Digivices that their human partners have. In some cases, as in the first series, the DigiDestined (known as the 'Chosen Children' in the original Japanese) had to find some special items such as crests and tags so the Digimon could digivolve into further stages of evolution known as Ultimate and Mega in the dub.
Is there an answer to this question: What effect does digivolution have on digimon?

Answer:
changes their appearance and increases their powers
