Step-by-step explanation:
The sentences in the question are simple sentences. They have a subject and a predicate, and they can stand alone since they convey a complete thought.
We need to transform them into complex sentences, which means a part of them needs to become a dependent clause. Dependent clauses have a subject and a predicate, but they cannot express a full thought.
To do so, we choose the suitable part of the sentence and give it a subject and a verb:
"weather permitting" --> if the weather permits
"A wounded tiger" --> when a tiger is wounded
Notice that we also added subordinating conjunctions such as "when", "if", or "because" to establish the relationship between the clauses.
