守る: keeping time and taking part in protection
Read punctuality linked to 出発できた and participation in protecting forest animals, keeping the targets and reported results within each sentence.
守る (まもる): keeping time
「皆が時間を守ったので、予定どおり出発できた。」 (“Everyone was on time, so we left as scheduled.”) Punctuality is linked to being able to depart. 出発できた presents departure as possible; the sentence does not identify transport or an exact departure time.
The English translation says left as scheduled. Read that wording alongside 出発できた without changing the quotation or adding details about the journey.
Taking part in protecting forest animals
「森の動物を守る活動に参加しました。」 (“I joined an activity to protect forest animals.”) This reports participation in an activity protecting forest animals. Participation does not establish that every animal was rescued or protection was completed.
Identify the target of protection and the participant's action. The sentence does not give animal numbers or changes to the forest's whole ecosystem.
Separate the target from the reported action
Keeping time and protecting animals give different targets of 守る. Identifying the target avoids narrowing both uses to the same physical defensive action.
Being able to depart through punctuality and joining a protection activity also report different scopes of result. Do not expand participation into success or fill in unstated targets and times.
Does joining an activity to protect forest animals mean every animal was rescued?
Show the answer and why
No. Participation alone does not establish complete rescue. The punctuality example's 出発できた also does not supply a transport type, exact time, or additional travel result.
