Answer: reliable but not valid
Explanation: Reliability does not translate to validity. This can be proved using the behavior of John's oven which has exhibited consistency in functionality and performance which defines that the readings and output are reliable. However, even though John's oven has exhibited constant output reliability due to its ability to consistently give similar readings or performance levels for about a month, the consistent performance which has been showcased by the oven seems to be faulty as food seem to get burnt regularly. This consistent output or performance level lacks validity as the temperature Guage incorrectly shows temperature which is 50 degrees cooler than the actual oven temperature.
