[header] How to create a christmas tree forest [title] Consider the type of tree you want to plant. [step] There are a wide variety of christmas trees and include fir, pine, spruce, cypress, and cedar. These trees thrive in different climates and look different from one another. <sep> (A) It is important to research the tree before setting up your tree to try it out to make sure you can write the tree's growing season so that you can get the most supplies you need. If you're just interested in having a tree stand out, then make sure to check for the following : [substeps] Spruce trees. (B) [substeps] Trees green may be used in a mix of green and evergreen. Greens, such as pintos and olive oil, may be more delicate than these. (C) Where the trees grow together is up to you. [substeps] Spruce trees light up the night for hours in the morning and drown out the morning sunrise between afternoons. (D) Think about where your tree forest will be located and choose a tree that can thrive in that climate. [substeps] Balsam firs are a popular christmas tree species that grow in the northern united states and canada, in hardiness zones 3-5 or states like minnesota, north dakota, and montana.

Now, solve this instance: [header] How to get off the phone quickly [title] Explain it isn't a great time. [step] You're busy with a project, have a deadline and you're trying to get a certain task done, etc. Ask if they can call you back and give them a better time. <sep> (A) [title] Talkers sometimes don't understand subtle hints so it's alright to insist you get back to them later. [title] Starting chatter with them only makes it harder to get off the phone. (B) Using an apologetic tone, ask them why they call you. They might have extra work to do or might need a bit of a heads up in the middle of that call. (C) Yes; there's a reason you probably need to do your most important tasks early; but you can also occupy your mind with other things without involving the person who is calling you on the phone. A great way to gently redirect the call is by saying it is urgent and you're stuck for 10 minutes. (D) [title] Say that whatever the time is, you'll call back again, within 24 hours. [step] Alternatively, you could text them again, but explain that you have to be somewhere, so just ignore them.
