Answer:
Hybridization may drive rare taxa to extinction through genetic swamping, where the rare form is replaced by hybrids, or by demographic swamping, where population growth rates are reduced due to the wasteful production of maladaptive hybrids. Conversely, hybridization may rescue the viability of small, inbred populations. Understanding the factors that contribute to destructive versus constructive outcomes of hybridization is key to managing conservation concerns. Here, we survey the literature for studies of hybridization and extinction to identify the ecological, evolutionary, and genetic factors that critically affect extinction risk through hybridization. We find that while extinction risk is highly situation dependent, genetic swamping is much more frequent than demographic swamping. In addition, human involvement is associated with increased risk and high reproductive isolation with reduced risk. Although climate change is predicted to increase the risk of hybridization‐induced extinction, we find little empirical support for this prediction. Similarly, theoretical and experimental studies imply that genetic rescue through hybridization may be equally or more probable than demographic swamping, but our literature survey failed to support this claim. We conclude that halting the introduction of hybridization‐prone exotics and restoring mature and diverse habitats that are resistant to hybrid establishment should be management priorities.
Explanation:
The jazz singer film released in 1927 was the first successful talking motion picture. The correct option is C. The Jazz Singer was the first feature-length film with synchronized dialogue when it was released in 1927.
<h3>When did movies sound to 1927?</h3>
The Warner Bros. film "The Jazz Singer," starring Al Jolson, was the first commercial feature film to use actual synchronized dialogue. "The Jazz Singer" was released on October 6, 1927, and it included both silent and sound sequences.
The Jazz Singer, which debuted on October 6, 1927, was the first feature film to be presented as a talkie. It was a big hit, and it was made with Vitaphone, the leading brand of sound-on-disc technology at the time.
Thus, the ideal selection is option C.

Answer:
President Andrew Johnson's plans for Reconstruction were the same as President Lincoln's plans: The union would be reunited, and the South should not be punished. Johnson planned to do this by pardoning Southerners who, though they took part in the war, pledged allegiance to the United States.
