In most cases yes.
A pronoun opener introduces a pronoun in a sentence and helps avoid repetition of a noun. For example, in the sentence "Mary went to the store. She bought groceries," "She" is the pronoun opener that refers back to Mary without restating her name.
A prepositional opener is a type of sentence structure where a prepositional phrase is used at the beginning of a sentence to provide additional information or context. It can help set the scene or clarify the relationships between different elements in a sentence.

The can opener was invented before the microwave. The first can opener was patented in 1855, while the microwave oven was not invented until 1946. Can openers were developed to open sealed cans, which became popular in the early 19th century for preserving food, whereas microwaves were developed much later as a cooking appliance utilizing electromagnetic radiation.
