Explain the rule that governs the pronunciation of the word "tea."

In the case of tea, its pronunciation consists of a short "e", pronounced as how the vowel "e" is called, whereas the letter "a" is not taken into account - this letter is not pronounced, it is simply used to determine the correct pronunciation of the whole word. This pronunciation applies as long as the compound ea is not followed by any letter.

dependent clause!

example: "before the food gets cold"

the correct answer is option d. none of these. it is noted that options a, b, and c share the same content.

despite the valid answer provided at the last sentence of each of the options, a question/answer format shouldn't include humourous themed responses such as "you bet your thermal pj's we do." - unless of course, the answer is carried out in an informal environment. this could be replaced with a simple "yes" or "it is necessary".

the question should be re-phrased to a more appropiate syntaxis. instead of "do we need the greenhouse effect? ", it should be written as "is the greenhouse effect necessary? " in order to give it a general scope, instead of limiting the answer to the needs of "we" the humans.
