Answer 2

To convert the given sentences into passive voice, you need to rearrange the sentence structure so that the subject of the sentence is the recipient of the action, and the doer of the action comes at the end, introduced by the preposition "by".

Here are the sentences converted into passive voice:

1. "The first computer to make in the USA." - Passive: "The first computer was made in the USA." 2. "Radium and polonium to discover Maria Curie." - Passive: "Radium and polonium were discovered by Maria Curie." 3. "The first accurate clock to design in 1657." - Passive: "The first accurate clock was designed in 1657." 4. "Robert Goddard to launch the first rocket in 1926." - Passive: "The first rocket was launched by Robert Goddard in 1926."

Please note that in the passive voice, the focus is on the action and/or the recipient of the action, rather than the doer of the action. The passive voice is often used when the doer of the action is unknown, unimportant, or should get less emphasis than the recipient of the action , , , , , .
