Yes, your origin server needs to have outbound ports 80 (HTTP) and 443 (HTTPS) open to allow Cloudflare's edge servers to connect and fetch your content. If your origin server is behind a firewall, ensure these ports are permitted for outgoing connections to Cloudflare's IP ranges.

Read these lines from the poem.

Let the proud white man boast his flocks,

And fields of foodful grain;

My home is ’mid the mountain rocks,

The desert my domain.

What do these lines reveal about the Bushmen's viewpoint?

(a) The Bushman resents the white man's greediness in clearing land to farm and raise livestock.

(b) The Bushman is impressed by the ability of the white man to farm and raise livestock.
