Answer to Question 1

TRUE

Answer to Question 2

The escape speed allows an object moving fast enough to overcome the gravity of a body and escape into space. But for very massive black holes, if you are so close as to be within the event horizon, now this speed is greater even than c, the speed of light, so neither matter nor even energy can escape the gravity of the black hole.

Though Candida and Aspergillus species are the most common fungal pathogens causing invasive fungal disease in the immunocompromised, infections due to previously uncommon hyaline and dematiaceous filamentous fungi are occurring more often today. Rare fungal infections, once accurately diagnosed, may require surgical debridement, immunotherapy, and newer antifungals used singly or in combination with older antifungals, on a case-by-case basis.
