soul

3.Read the following passage and answer the question given below: Environmental toxins which can
affect children are frighteningly commonplace. Besides lead, there are other heavy metals such as
mercury, which is found frequently in sh, that are spewed into the air from coal-red power plants, says
Maureen Swanson, MPA, director of the Healthy Children Project at the Learning Disabilities Association
of America. Mercury exposure can impair children's memory, attention, and language abilities and
interfere with ne motor and visual-spatial skills. A recent study of school districts in Texas showed
significantly higher levels of autism in areas with elevated levels of mercury in the environment.
Researchers are finding harmful effects at lower and lower levels of exposure, says Swanson. They're
now telling us that they don't know if there's a level of mercury that's safe. Unfortunately, some of these
chemicals make good ame retardants and have been widely used in everything from upholstery to
televisions to children's clothing. Studies have found them in high levels in household dust, as well as in
breast milk. Two categories of these ame retardants have been banned in Europe and are starting to be
banned by different / states in the United States. The number of toxins in our environment that can
affect children may seem overwhelming at times. On at least some fronts, however, there is progress in
making the world a cleaner place for kids and just possibly, reducing the number of learning disabilities
and neurological problems. With a number of efforts to clean up the environment stalled at the federal
level, many state governments are starting to lead the way. And rather than tackle one chemical at a
time, at least eight states are considering plans for comprehensive chemical reform bills, which would
take toxic chemicals off the market.
All these are harmful effects of mercury in children EXCEPT
Affects driving skills
Causes attention decit disorder
Lead to neurological problems
Impacts ability to learn languages

PROGRAMMING:
1.Confused? Well it stands for Welcome To HackerEarth September Easy Challenge :). It's quite amazing
when long words like this get reduced to such a short string. They sound pretty cool and often make
the chat interesting. They are almost used everywhere these days.
Our friend Harsh has been recently reducing every sentence he receives to acronym. Since Harsh is a
young lad he has his own personal likes and dislikes. There are some words which he just does not want
to see in a sentence. So whenever he encounters such a word he simply ignores it. Harsh is thinking of
converting a book to an acronym book where each sentence of the book is reduced to its short form.
Since Harsh is quite busy in promoting his new book he wants you to help him in doing so.
So he gives you a set of words which he dislikes and a sentence for which he wants to abbreviate. Help
him in getting the required abbreviation.
Input Format
The first line contains an integer K which denotes the number of disliked words, This is followed by k
lines where each line contains a disliked word, the next line will contain an integer donating the number
of words in the given sentence, The last line contains the sentence of which Harsh wants to abbreviate.
The sentence will consist of number of words separated by a space
All words will consist of lowercase English alphabets(a-z)
Constraints
1<= K <=10
1<= length of each word <=100
1<= length of the sentence <=100
Output Format
In a single line print the required acronym. The Acronym should be printed in Upper Case English
alphabets separated by "." (dots)
Changing a sentence to an acronym means taking the first character of each word of the sentence and
changing it to upper case then writing the characters separated by "." (dots), remember that Harsh
doesn't like some words so he will not take their first character if they appear in the sentence
If a disliked word is present as a proper substring of a word in the given sentence then it should not be
ignored.
The final Output will never be an empty string.
