Explanatory Answer

Express the number 120 as a product of powers of prime factors.



In this case, 120 = 2^3 * 3 * 5.



The three prime factors are 2, 3 and 5.



The powers of these prime factors are 3, 1 and 1 respectively.



To find the number of factors / integral divisors that 120 has, increment the powers of the prime factors by 1 and then multiply them.



In this case, (3+1) * (1 + 1) * (1 + 1) = 4 * 2 *2 = 16.

The health commissioner said that the government had implemented strict measures to eradicate the contaminated food and, despite the recent illnesses, it will try to prevent the outbreak from reccurring in the future.

King Kong,whenever u see a participle phrase being used in a sentence, check whether the phrase is in active or passive voice.If it is in active voice use-'ing' form & if in passive voice use 'ed' form.Its a final word on such types of Questions.No ifs & buts.

In this quest,the fungus is extending itself but is spawned by..blah blah,hence the use of ing & ed at appropriate places.

First, you should know that such + noun + as to is much less common than so + adj/adv + as to.



Now, for the difference between these two. I think these are best illustrated with examples:



Xue Mei spoke in such a way as to calm us down.



The sales materials are presented in such a way as to encourage attendees to purchase the products on the spot.



These usages focus on doing an action and paying to that action while you are doing it so that the action creates a result. To simplify a bit, these usages answer the question, "Why did you do it in that way?"



So, the most common words to use with this pattern are way, manner, etc.



Compare these similar sentences:



Xue Mei spoke so that we would stop asking her questions.



The sales materials are presented at the end of the meetings so that the participants won't realize the meeting is actually a sales presentation.



The part that comes after so... that... answers the question WHY.

To quote Michael Swan:



Because puts more emphasis on the reason, and most often introduces new information. When the reason is the most important part of the sentence, the because-clause usually comes at the end. It can also stand alone.



For introduces new information, but suggests that the reason is given as an afterthought. For-clauses never come at the beginning of sentences, and cannot stand alone. For used in this sense is a formal written style.

She runs faster than I.

She runs faster than do I.

She runs faster than I do.



All three are grammatically correct. The first is best because it is the most concise. There is no need for the "do" in this case because there subject pronoun "I" is clearly being compared with the subject "she." A verb such as "do" or "does" or "is" is necessary after "than" only when there are both a subject and an object before.



Example:

"Martin likes football more than his wife." Ambiguous. It is not clear whether "wife" is being compared with "Martin" or "football."

Should be either:

"Martin likes football more than does his wife."

Or:

"Martin likes football more than his wife does."

[Both of these compare "wife" with "Martin."]

Or:

"Martin likes football more than he likes his wife."

Or:

"Martin likes football more than he does his wife."

[These last two versions compare "wife" with "football."]



No verb is needed after "than" when there is no object. Example:

"Martin drives faster than his wife."

You could write:

"Martin drives faster than his wife does."

Or:

"Martin drives faster than does his wife."

But the "does" is not really necessary because there is only one noun ("Martin") with which "wife" could be compared.



In any case, "she runs faster than me" is not grammatically correct. "Than" is not a preposition and does not require the object pronoun. "She runs faster than I" is short for "she runs faster than I do."

I have been reading this board for quite some time and it has proved to be very helpful. I was wondering if anybody could help me with the following two SC. Both of 'em test the concept of "like" vs "as" and somehow it is driving me crazy. My basic understanding that "like" is used for nouns and "as" for verbs somehow doesn't work here. Any comments are highly appreciated. Thanks!
