A semi-trailer truck is the combination of a tractor unit and one or more semi-trailers to carry freight. A semi-trailer attaches to the tractor with a fifth wheel hitch, with much of its weight borne by the tractor.

It is variously known as a transport in Canada; semi or single in Australia and New Zealand; semi, tractor-trailer, big rig, or eighteen-wheeler in the United
â¢ APA stands for American Psychological Association. MLA stands for Modern Language Association. â¢ When it comes to what is expected in the APA format, these are the things you should include. A title page, page numbers, abstract, headings, thesis statement, evidence for your research and bibliography. For a MLA research paper, no title page is required.
The reference title should be underlined or enclosed in quotation marks. Both MLA and APA styles of writing have their own unique features. There are researchers who advocate the MLA style of writing because it helps in easier organization of content and is the most common style used.
