What are the two main components of an if statement?

Select one answer, then check.

• A conditional and a body.
  Correct. The reading names these as the two essential parts: the conditional (the expression after the if keyword) and the body.
• A conditional and a consequence.
  Not quite. The reading never calls the second part a "consequence"; it is the body.
• A question and a body.
  Not quite. The reading describes the conditional as being "like" a question, but its name is the conditional.
• A question and a consequence.
  Not quite. Neither "question" nor "consequence" is the term the reading uses for these two parts.

Which of the following is NOT a valid conditional?

Select one answer, then check.

• A Python assignment of a value to a variable.
  Correct. An assignment is a statement, not an expression, so it can never appear after the if keyword; if x = 5: is a syntax error.
• A boolean value.
  Not quite. A boolean value is exactly what a conditional is supposed to be.
• The result of using the equality or greater-than operators.
  Not quite. The reading gives this as its example of a valid conditional.
• An empty string, the integer 0, the float 0.0, and the special value None.
  Not quite. These are valid conditionals too; thanks to Truthiness they are simply the values that evaluate to False.
