Question

1. what does the speaker mean by referring to \this garden\?

a patch of dandelions
nature
a flower bed
home

Explanation:

Without additional context, it's difficult to be certain. However, "this garden" most directly refers to a physical area with plants. A patch of dandelions is a specific plant - filled area. Nature is too broad, a flower - bed is a part of a garden but not the whole, and home is not related in a typical sense. A patch of dandelions is the most likely literal interpretation of a garden - like area among the options.

Answer:

a patch of dandelions
