-더라도 means even if or even though and shows concession: the second part still happens despite the first condition.

So 자원봉사자가 적더라도 means even if there are few volunteers.

Compared with -아/어도, -더라도 often sounds a bit more emphatic or formal, especially in written statements or rules.

Here, -가 marks 자원봉사자 as the subject of 적다.

• 자원봉사자가 적다 = there are few volunteers

Using -는/은 would shift the nuance toward topic or contrast, like as for the volunteers...

In this sentence, the structure is:

• 자원봉사자가 적더라도 = even if the volunteers are few
• 담당 구역은 모두 확인합니다 = as for the assigned areas, all are checked

So -가 is natural for the condition, while -은 is used later to highlight the areas.

No. Here 적다 means to be few or to be not many.

So:

• 사람이 적다 = there are few people
• 돈이 적다 = there is little money

It is about quantity, not physical size.

If you wanted to say small in size, you would usually use 작다 instead.

Korean often does not mark plural when the meaning is already clear.

In this sentence, 자원봉사자가 적다 already strongly suggests volunteers in general, so -들 is unnecessary.

• 자원봉사자가 적더라도 = even if there are few volunteers
• 자원봉사자들이 적더라도 = also possible, but a bit heavier and usually less neutral

Korean uses plural marking more selectively than English.

담당 구역 is a noun phrase made of:

• 담당 = being in charge of, assigned responsibility
• 구역 = area, zone, section

So 담당 구역 means the assigned area(s) or the area(s) someone is responsible for.

Depending on context, it could mean:

• zones assigned to volunteers
• sections assigned to staff
• areas a team must inspect

This is a very common Korean pattern. The thing that would logically be the object can be marked with 은/는 instead of 을/를 when it is being presented as the topic or given a contrastive feel.

So:

• 담당 구역을 모두 확인합니다 = we check all the assigned areas
• 담당 구역은 모두 확인합니다 = as for the assigned areas, we check all of them

Using 은 here adds a nuance like:

• at least regarding the assigned areas
• those assigned areas, specifically, are all checked
• those areas are definitely covered

So it is not wrong at all; it just adds topical emphasis.

모두 means all.

In this sentence, it means that all of the assigned areas are checked.

Even though 모두 appears right before the verb, its meaning applies to 담당 구역:

• 담당 구역은 모두 확인합니다
  = all the assigned areas are checked

This is normal in Korean. Words like 모두, 다, 잘, 빨리 often appear before the verb.

확인합니다 is in the formal polite style, often called 합니다-style.

It is commonly used in:

• announcements
• reports
• instructions
• workplace communication
• official writing

It sounds more formal than:

• 확인해요 = polite conversational
• 확인해 = casual

Also, the present tense here does not have to mean only right now. It can describe:

• a routine
• a policy
• a standard procedure

So the sentence can sound like a general rule: Even if volunteers are few, all assigned areas are checked.

No, not in normal usage.

• 적더라도 = even if it is few / even if there are few
• 적어도 usually means at least

So these are very different in meaning:

• 자원봉사자가 적더라도 = even if there are few volunteers
• 자원봉사자가 적어도... would usually be understood differently and may sound confusing because 적어도 is commonly read as at least

That is one reason 적더라도 is clearer here.

Korean often leaves the subject unstated when it is obvious from context.

So 확인합니다 does not explicitly say who performs the action. Depending on the situation, it could mean:

• we check
• the staff checks
• the team checks
• one checks

English usually wants an explicit subject, but Korean often does not need one.

So the sentence focuses less on who does it and more on the policy or action itself: all assigned areas are checked, even if volunteers are few.

It can be either, but it most naturally sounds like a general practice, rule, or policy.

Because it uses 확인합니다 in formal style, it often feels like:

• a standard procedure
• an instruction
• an official statement

So the sense is often:

Even if there are few volunteers, all assigned areas are checked.

If the speaker wanted to strongly emphasize a one-time future action, Korean might use other clues from context or add time expressions.
