Note also that there is an important Touchstone in your textbook captioned V&M Star Steel $v.$ Centimark, which is another important example of res ipsa claim analysis by a real court. Look that case up in your book and answer this question: what happened in the case with respect to the inference of res ipsa loquitur that was claimed on the facts?

plaintiff asked for an inference of res ipsa but it was denied

more than one of the other answers, but not all, are correct

plaintiff asked for an inference of res ipsa and it was granted

defendant asked for an inference of res ipsa and it was granted

defendant asked for an inference of res ipsa but it was denied
