Final answer:
The claim that only Times New Roman and Calibri are acceptable for academic writing is false. There are various standard fonts like Arial and Garamond that are also often accepted in academic settings, depending on specific institutional guidelines.
Step-by-step explanation:
The statement that the two acceptable fonts and sizes in academic writing are Times New Roman or Calibri is false. Academic writing does often require the use of standard fonts for readability and a professional appearance, but there are more options than just Times New Roman and Calibri. Academic formatting requirements usually stipulate 12-point font size and may also include other fonts such as Arial or Garamond, among others. It is always important to follow the specific guidelines provided by your instructor or the institution, as these may vary.
When discussing typography, it's essential to note that there are two basic letterforms: serifed and sans-serif. Serif fonts, like Times New Roman, include small decorative lines (serifs) at the end of the stroke of the letters, and are often viewed as traditional and formal. In contrast, sans-serif fonts, like Calibri and Helvetica, do not have these embellishments and tend to offer a cleaner, more modern appearance.
