fcoincided with)

- verb, we must use a noun or gerund as
a subject and so we have to change "He went to 'His going

(b) BAD C
Note that after without', which is, a preposition, we may use only a noun, pronoun or gerund. This is also true of other prepositions.
He is fond of Chinese food.
He is fond of eating Chinese food.
She is tired of school.
She is tired of going to school. - Therefore, in our answer we have used "letting. Let', however, is always followed by an infinitive without "to", so the word 'finish' must come next in our answer and as 'finish' is followed by a gerund, we must use the word asking' next. For further information on which words in English are usually followed by gerunds and which are usually followed by infinitives, refer to the Answer Book to EFFECTIVE ENGLISH E.F. O'NEILL - H.K. WITMAN PUBLISHING CO. pages 35

First let's briefly discuss the differences between also, too, so", "nor, either and "neither.
Too, so and also. Too' and also have exactly the same meaning but they often appear in different positions in the sentence.
He is also tall. He is tall too.
He also likes coffee. He likes coffee
too.
She also speaks English. She speaks English too.
for emphasis, we may also put the "too" in front of the verb:
He too is tall.
He too likes coffee.
He too speaks English.
Note especially that too and also can never be used with 'not', 'never', 'nor', 'no- body, or other negative words.
When "so' is used with the meaning of also, it must be the first word in a sen. tence and is usually used to introduce a shortened type of sentence.
Peter is a good swimmer. So is George. Tom-likes apples. So does Lawrence. Either, neither and nor, Either when having the meaning of 'also" is used with a negative word.
Helen is not a good swimmer either. Tom never comes here either.
'Nor' and 'neither mean 'not.... either' and usually appear at the beginning of a shortened type of sentence, although 'neither' may be used after 'and',
Peter is not a good swimmer. Neither is George.
Peter is not a good swimmer. Nor is George:
Tom doesn't like apples. Neither does Lawrence.
Tom doesn't like applies. Nor does Lawrence.
"Neither" may also be used after 'and' but 'nor may not be.
Tom doesn't like apples and neither does Lawrence.

Notice that if we were to write the sen- tence 'neither does Pamela' in its complete- form, we should have to write:--:
Neither does Parmela ever visit us.
We could not use seldom since the 'neither' at the beginning of the sentence is already negative.
Peter never comes here either. Neither does Peter ever come here.

neither
either
nor (neither cannot be used here because of the presence of the word 'even' which is similar in meaning "to either)

From the figure above, the expression 6.5x+5y gives the minimum value
under the constraints
when x1.5 and y=1.5 Therefore, the cost of the diet-6,5(1.5)+5(1.5) -17.25 (dollars)
Ans: The required cost
is 817.25.
