The technique that should be used to determine whether the sentiment in a Facebook post is positive or negative is Classification.

Here's why:

1. Understanding the Task: The task here is sentiment analysis, which involves determining whether a piece of text (in this case, a Facebook post) is positive or negative. This is a type of text classification problem, where the goal is to categorize text into a set of predefined classes.

2. Classification: In machine learning, classification refers to a predictive modeling problem where a class label is predicted for a given example of input data. Examples of classification problems include spam detection, churn prediction, and sentiment analysis.

3. Applying Classification to Sentiment Analysis: For sentiment analysis, you would use a classification algorithm to train a model on a dataset of Facebook posts where the sentiment is already known (this is your training data). Once the model is trained, it can predict the sentiment of new, unseen Facebook posts.

4. Why not Regression, Traditional Programming, or Clustering? Regression is used for predicting a continuous outcome variable (like house prices) from one or more predictor variables, so it's not suitable for this task. Traditional Programming involves writing explicit instructions for the computer to follow, which is not feasible for sentiment analysis due to the complexity and variability of human language. Clustering is a type of unsupervised learning that groups similar instances together, but it doesn't involve predicting a predefined class label (like "positive" or "negative").
