At about the same time that Antonio Meucci was filing patent caveats for his talking telegraph, Alexander Graham Bell was starting to work on his own telephone model. Bell was an expert in the field of elocution, or vocal speech. He was very skilled at teaching deaf students the challenging task of speaking aloud. Just like Meucci, he enjoyed experimenting. Bell also dreamed of a world full of useful telephones, just as Meucci did. However, he had something that Meucci did not. Bell had a wealthy father-in-law who was happy to invest in his dream. Based on the details of this excerpt, a reader can infer that

Meucci did not succeed because he was not as talented as Bell.
Bell’s expertise in elocution helped him to develop the telephone.
Bell succeeded because he had more financial resources than Meucci.
Meucci’s caveats prevented Bell from filing a patent for the telephone.
