This program does not work. There are three errors that you will need to fix:

TODO: Fix the following 3 errors.

ERROR #1) The compiler knows there is something wrong, and it will issue a
warning and and two error messages, all related to the same problem.
       Read the error and warning messages carefully to point you in the
       right direction. Did you know if you double-click on an error
       message (in the Error List) that it will take you to the spot in
       your program where the compiler detects the problem? Also, get
       in the habit of ALWAYS reading messages carefully. You may not
       understand them right now, but over time you will come to understand
       the messages better and better. One of these three messages will be
       most helpful, but it is still informative to see that the other two
       messages come as a result of this single problem.

ERROR #2) After fixing ERROR #1 your program will run. However, you will get
incorrect results. It will say "Congratulations!" even when not perfect.

ERROR #3)

But when you find and fix that error, something still lurks behind that the
compiler does not complain about and that will give incorrect output. The output
will still display a zero after the decimal point even if it should be .3 or .7...

IMPORTANT NOTE ON ERROR #3: You are NOT allowed to change the data type of any constant
or variable to make this work. You also MUST divide by NUM_OF_SCORES
when calculating the average.

Answer in detail please, high percentage of my grade

1) Discuss how fusion genes can originate from chromosomal breaks, and how these fusion genes can lead to cancer

b) Within your answer, please discuss in detail the genotype, and how this leads to the phenotype of at least one type of cancer

c) discuss the genetic screening techniques that can be used to assess this disorder, and any recent developments in this area

d) discuss how a detailed understanding of the genotype could lead to novel therapeutics for cancers originating from fusion genes

Lawmakers recently approved the Coronavirus Aid, Relief, and Economic Security (CARES) Act designed to address the public health and economic crisis brought on by the novel coronavirus (COVID-19) pandemic. The CARES Act appropriates roughly $2.2 trillion of spending, tax breaks, loans, and other resources over the next decade.  CBO estimates it would add $1.7 trillion to the deficit over that period. Assuming that there is no demand shock, discuss what effects you would expect the CARES Act to have on consumption, national savings, real interest rate, and investment.

Due to the COVID-19 epidemy, with so many working and studying remotely, the Internet’s capacity is under considerable strain. Unfortunately, this has put a huge load on Internet Service Providers (ISPs) and we can only expect the situation to worsen with time.

Propose a fix/solution to the TCP/IP protocol suite to help the Internet overcome its capacity bottleneck/s. For example, you may focus on fixing a specific problem at a particular layer of the protocol stack or improving a known deficiency of a protocol or propose a completely novel method to improve network capacity.

The outbreak of Novel H1N1 flu virus in 2009 caused widespread anxiety throughout the world. However, the incidence of this flu was lower than anticipated. You may read more about H1N1 and its progress at http://www.cdc.gov/h1n1flu/cdcresponse.htm. Briefly describe the timeline of this outbreak and how it was investigated. Discuss why you think the incidence was low; include human and environmental factors that could have contributed. Be sure to support your opinions with scholarly evidence from your readings.
