Answer:
<h2>Positive Attitude</h2>
<h3> It has been said that a positive attitude is the key to success in life, I agree.</h3>
<h3>Having a positive attitude means to keep a set of ideas, values and thoughts that tend to look for the good, to advance and to get through problems, to find the positive outcome in every situation, to always look at things in life as there is always a brighter tomorrow.</h3>
<h3> A good attitude or positive attitude is the outward explanation of a mind that dwells primarily on positive matters. It is a mind-set tipped in favor of creative activity rather than boredom, joy over sadness, hope over futility. A positive attitude is that state of mind which can be maintained only through conscious effort. When something jars one's mental focus into a negative direction, those who are positive know that in order to bounce back adjustments must be made.</h3>
Answer:
The answer to your question would be that the revision that combines the sentence using a subordinating clause and subordinating conjunction is the following one: East Antarctica is covered by massive layers of ice which is thousands of meters thick.
Explanation:
The revised version of the sentence includes an essential relative clause. Essential relative clauses limit an ambiguous noun, that is, they complete the meaning of the sentence. The essential clause helps identify the noun it modifies. Consequently, if they are dropped, the meaning of the sentence is altered (see 1).
1) East Antarctica is covered by massive layers of ice
