The leaders were . . . . . . . needed by those to . . . . . . . they were addressed.

angrily , who
readily , which
scarcely , whom
rarely , where E. joyfully , when

The correct answer is: B. readily, which

The leaders were readily needed by those to which they were addressed. This means that the leaders were always available to help those who needed them.

The other options are not correct because they do not make sense in the context of the sentence.

  • Angrily, who does not make sense because it is not clear who is angry.
  • Scarcely, whom does not make sense because it is not clear who is scarcely needed.
  • Rarely, where does not make sense because it is not clear where the leaders are rarely needed.
  • Joyfully, when does not make sense because it is not clear when the leaders are joyfully needed.

I hope this helps!
