"Hard" has two meanings but "difficult" only has one. Hard can mean a physical property of a substance, for example, "The concrete is hard," or "wood is hard." Hard can also be synonymous with "difficult." "The test was hard," or "it was hard work." Difficult is just used to describe tasks or actions. "The test was difficult," or "it was difficult work," or "the French horn is a difficult instrument," mean the EXACT same thing as "the test was hard, "it was hard work," or "the French horn is a hard instrument." Difficult can NOT be used to describe physical things. "The concrete is difficult," or "the wood is difficult," are incorrect and meaningless statements. Hope I helped!

Your question is unclear? Do you mean "tip" as in "tip in a restaurant?"

"I think that one of the reasons is that why people tye-dye their shirt is just to individualize it." Change it to "I think that one of the reasons people tye-dye their shirt is just to make it distinguish it." The phrase "is that" is not necessary. "The huge noise caused a pandemonium to occur." Change to "The loud noise caused pandemonium." The phrase "huge noise" is awkward in english, sounds are almost always described with specific words, "Loud, quiet, soft, etc" but never "big" or "small." Pandemonium is a noun but is almost never used with an article (a, the, that, etc). No matter how you word it, it will stay as a generalization. Change to "No matter how you word it, it is a generalization." In this context the word "stay" is implied. Phrases that express the idea that something is inchangable no matter what one does are expressed with this construction. "No matter *the action*, *subject* *verb* He is less than six feet tall. No change needed. John is as biased as that police officer. No change needed, though you might say "John is just as biased..." Just as can mean "exactly as." You are stubborn as he is. No change needed. The product is newer than new. This could be found in some contexts but normally in english we say "This product is brand new." Hope that helped.

"THE Soan River Basin FEATURES the Pot War Plateau." You must put "the" before "Soan River Basin" because it is a proper noun and a definite place. In English physical locations must have "a" or "the." "We're going to A mountain." "I saw THE Empire State Building." "The" is appropriate in your sentence because "a" would mean there are many different "Pot River Basins." "Featurizes" is a great guess at an English word but not correct. The verb you are looking for is "features" which means "to make featured." BUT you are correct that the suffix "izes" is used in the same way in many other english words such as "collectivizes" or "satirizes." Keep it up!
