+Scala Assessment
+-------------
+
+#### Q1. Scala bytecode can run on top of Java VM. What is the fundamental difference between Java object.clone() and Scala object.copy()?
+
+- [ ] One is a Java object, the other is a Scala object.
+- [ ] clone() will copy class structures but not the data, while copy() will also copy data into new objects.
+- [ ] There is no difference.
+- [ ] copy() allows you to change values during the copying process; clone() does not.
+
+
+#### Q2. What value does this code return? 
+
+```
+val m1 = Map("a"->1,"b"->2,"c"->3)
+m1("a")
+```
+
+- [ ] a
+- [ ] 2
+- [ ] b
+- [ ] 1
+
+
+#### Q3. What is one way to avoid low-level parallelization details?
+
+- [ ] monads
+- [ ] literal functions
+- [ ] partially applied functions
+- [ ] parallel collections
+
+
+#### Q4. What do you use in ScalaTest to see a detailed diagram of error messages when a test fails?
+
+- [ ] ArgumentExceptions
+- [ ] AssertionException
+- [ ] DiagrammedAssertions
+- [ ] JUnit
+
+
+#### Q5. What data type would you use to store an immutable collection of objects that contain a fixed number of varying types?
+
+- [ ] Array
+- [ ] ImmutableCollection
+- [ ] List
+- [ ] Tuple
+
+
+#### Q6. After defining a function in the interpreter, Scala returns the following. What does the 
+
+```
+myfnc: ()Unit
+```
+
+- [ ] The function has no side effects.
+- [ ] The function takes no parameters. 
+- [ ] The function returns no value.
+- [ ] Returning unit types to the function is a closures.
+
+
+#### Q7. What type of number is 1234.e5?
+
+- [ ] hexadecimal
+- [ ] short
+- [ ] floating point
+- [ ] long
+
+
+#### Q8. When you convert a map to a list using the toList method of the map, the result will be of which type?
+
+- [ ] List[(String, String)]
+- [ ] List[(Array, Array)]
+- [ ] List[(Array, Array)]
+- [ ] List
+
+
+#### Q9. What type of object does this code create? 
+
+```
+val x = (1234, "Active")
+```
+
+- [ ] List
+- [ ] Map 
+- [ ] Tuple
+- [ ] Array 
+
+
+#### Q10. Which is a subclass of all classes?
+
+- [ ] AnyVal
+- [ ] AnyRef 
+- [ ] Method
+- [ ] Null
+
+
+#### Q11. For the for-yield construct, is the scope separate between for-body and yield-body?
+
+- [ ] Yes and no. It is different depending on the for construct and what it does.
+- [ ] Yes, because the for section does not expose its scope.
+- [ ] No, because for-yield shares the same scope, even though they are within separate curly braces.
+- [ ] Yes, because they are within different curly braces.
+
+
+#### Q12. What is one way to implement pattern matching on methods?
+
+- [ ] using regex
+- [ ] using monads
+- [ ] using string matching
+- [ ] using case classes
+
+
+#### Q13. What is the value of z after executing this code? 
+
+```
+val y = List('a','b')
+val z = y::List('c') 
+```
+
+- [ ] List(a,b,c)
+- [ ] List(List(a, b), c)
+- [ ] List(c,a,b)
+- [ ] List(c,List(a,b))
+
+
+#### Q14. What term is used to specify a precondition?
+
+- [ ] assert
+- [ ] require
+- [ ] precondition
+- [ ] mustHave
+
+
+#### Q15. Which Scala type may throw an exception or a successfully computed value, and is commonly used to trap and propagate errors?
