Many of our beliefs about the universe are based on inductive reasoning, also known as the     1     (science) model. This means of arriving at the truth requires the observation of concrete events     2     (follow) by the development of a theory to explain what has been observed. In other words, it is a way to proceed from the particular to the general, from the specific to the abstract. However, it is in the nature of scientists to inquire into every possibility,     3     this means they often discover things no one has ever seen or noticed before. Our generalized theories therefore never cease     4     (change).

In fact, most of our new knowledge     5     (gain) by the observation of things we have never seen before. Before the first black swan was seen, the assumption was that all swans were white,     6     is known as the “black swan theory”. How could we have known otherwise? There will always be “unknown unknowns” such as black swans, but some people criticize those who dare to suggest their     7     (exist). We should always be objective and question     8     we think we know.

The world in the future is bound to be different from now. However much we understand, there will always be     9     remote possibility of discovering “a black swan”. Accordingly, our     10     (comprehend) of the world will change. Therefore, we should keep up with new developments in all domains of knowledge — “black swans” can change history.

Our communication is dependent not only on the words we use, but also on how we use them. Communication is the process of exchanging information between a sender     1     a receiver. The sender encodes a message and sends it face to face, or through video, telephone, mail or social media. This message is then     2     (receive) and decoded by the receiver. In response, the receiver sends an encoded message back,     3     is referred to as feedback. This feedback is decoded by the original sender and the entire cycle     4     (repeat) itself until they have finished communicating.

This communication process can be challenging but, with practice and patience, you can become a highly competent communicator.     5     (accomplish) this, you need to know with whom you are communicating. Depending on whether you are communicating with a stranger, friend, family member     6     co-worker, you will need to decide which communication channel best suits the situation. Furthermore, you will need to determine the appropriate style to use and     7     complex your choice of words should be. For example, if you are a business person     8     (negotiate) with a large enterprise about a deal, you should do it face to face, using formal language in a straightforward manner. Meanwhile, your body language is     9     (equal) important and the value of empathy should not be understated.

Effective communication will enable you to settle differences and disagreements appropriately and improve your     10     (interaction) with others. Good communication skills will also help you build trust and gain respect, allowing relationships to become more positive and productive.
