Question: Can COVID-19 be spread by a person who has no symptoms

Answer passage (source: WHO):
page_title: Q&A on coronaviruses (COVID-19)
section_headers: Can COVID-19 be caught from a person who has no symptoms?
section_content: COVID-19 is mainly spread through respiratory droplets expelled by someone who
is coughing or has other symptoms such as fever or tiredness. Many people with
COVID-19 experience only mild symptoms. This is particularly true in the early
stages of the disease. It is possible to catch COVID-19 from someone who has
just a mild cough and does not feel ill.
Some reports have indicated that people with no symptoms can transmit the
virus. It is not yet known how often it happens. WHO is assessing ongoing
research on the topic and will continue to share updated findings.

Reviewer feedback on this answer:
This answers the question directly. It also goes on to talk about symptoms a person may have, or that they may not even feel ill.
This would be better if the two paragraphs were switched around. P2 gives the actual answer whereas P1 may be true, it doesn't have studies to back it up. Thus P2 is the stronger argument.

Answer passage (source: WHO):
page_title: Q&A on coronaviruses (COVID-19)
section_headers: What should I do if I have no symptoms, but I think I have been exposed to COVID-19? What does it mean to self-quarantine?
section_content: To self-quarantine means to separate yourself from others because you have
been exposed to someone with COVID-19 even though you, yourself, do not have
symptoms.During self-quarantine you monitor yourself for symptoms. The goal of
the self-quarantine is to prevent transmission. Since people who become ill
with COVID-19 can infect people immediately self-quarantine can prevent some
infections from happening. .
In this case:

Have a large, well-ventilated single room with hand hygiene and toilet facilities
If this is not available place beds at least 1 metre apart.
Keep at least 1-metre distance from others, even from your family members.
Monitor your symptoms daily
Self-quarantine for 14 days, even if you feel healthy
If you develop difficulty breathing, contact your healthcare provider immediately – call them first if possible.
Stay positive and energized by keeping in touch with loved ones by phone or online, and by exercising yourself at home.

However, if you live in an area with malaria or dengue fever it is important
that you do not ignore symptoms of fever. Seek medical help. When you attend
the health facility wear a mask if possible, keep at least 1 metre distant
from other people and do not touch surfaces with your hands. If it is a child
who is sick help the child stick to this advice.

Reviewer feedback on this answer:
This does not answer the question. It talks about how to self quarantine, not if a person without symptoms can spread the virus.
Totally focused on the wrong thing. The question is not about self-isolation; it's references asymptomatic transmission.

Answer passage (source: WHO):
page_title: Q&A: Adolescents, youth and COVID-19
section_headers: Can adolescents spread COVID-19 to other people even if they have mild or no symptoms?
section_content: Yes. Infected people in all age groups – including adolescents - can transmit
the virus to other people, even if they have mild symptoms or do not feel ill.
The virus is spread from person to person through small droplets from the nose
or mouth which are spread when a person with COVID-19 coughs, sneezes or
speaks. These droplets can land on objects and surfaces. People can then
become infected by touching these objects or surfaces, and then touching their
eyes, nose or mouth.

Reviewer feedback on this answer:
A little strangely worded including adolescents since the question has nothing to do with age. But other than that it's ok background info on transmission.
This not only answers the question but also tells me how it can be transmitted.
