Precisamos colocar os verbos no passado, conjugando-os, ou utilizando o "did", conforme a orientação dada pela questão.

Explicação:

James Clerk Maxwell didn't create the first radio. He developed the first radio-wave mathematical formula. In 1888, Heinrich Hertz tested Maxwell’s assumption. The radio was a subdivision of telecommunication. “When did Oliver Lodge name the coherer?” “In 1894.” In 1888, Temistocle Calzecchi-Onesti demonstrated that a tube with iron filings conducted an electrical current. Radio communication involved the transmission of electromagnetic waves. Before the 19th century, many scientists I tried to invent something like the radio. Marconi noticed that electromagnetic waves traveled between two points separated by an obstacle.

O verbo "name" não muda de forma porque há uso de "did" antes, na mesma frase.
