Answer:
Reliable but not valid
Explanation:
Validity and reliability are two concepts in research study that is used for evaluating the quality of a research. They show how well a test, or a method measures something. Reliability is a measure of how consistent the test or measure is, while validity measures the accuracy level of the test or measure. In the example above, the measure is reliable, because the consistency of the result is not in doubt here, what is in doubt is how accurate the measure us. Here the respondents are unwilling to report unhappy feelings because they dont want to be judged, hence validity will be questioned here.

Answer: Apostle Paul
Explanation: The apostle Paul, who, before becoming a Christian, was called Saul, and was a fierce persecutor of Christians. The very fact that he persecuted Christians indicates that Paul was not one of Christ's closest disciples, but immediately after the dissemination of Christ's teaching began, Paul, then still Saul, experienced enlightenment. It happened on the road to Damascus, in another of his persecutions of Christians when, according to the Bible, Christ Himself appeared to Paul, after which Paul was blinded for a short time, then experienced enlightenment and converted to a Christian. So Paul's conversion can be thought of as early in Christianity. Paul was one of the most ardent Christians in the world, known for his epistles and conversion of Gentiles.

The Hubble sequence is a form of classification of galaxies invented by Hubble in 1926. The sequence divides galaxies into three main categories: lenticular, elliptical and spiral. There is a fourth category that is called irregular, where there are the galaxies that do not fit the characteristics to be included in the three previous categories.
This categorization is the most used even today by both amateurs and astronomers.
