• Which IBM computer defeated chess world champion Garry Kasparov in 1997?Artificial intelligence
• Sorting incoming mail into advertising and ordinary mail is which kind of AI task?Artificial intelligence
• Which natural language processing task decides whether the attitude in a sentence is positive or negative?Artificial intelligence
• What is most often counted when the size of a language model is compared?Artificial intelligence
• Which computer vision task finds people or cars in a photo and marks where each one sits with a box?Artificial intelligence
• Which method raises the amount of training material by flipping or cropping images when data is short?Artificial intelligence
• Ordering artificial intelligence, machine learning, and deep learning from widest scope to narrowest gives which sequence?Artificial intelligence
• Which technology reads a written sentence aloud in a human voice?Artificial intelligence
• What is the marker of the correct answer that is attached to each cat photo and fed in along with it?Artificial intelligence
• Which is the most basic performance measure for a classification model, the count of correct cases divided by the count of all cases?Artificial intelligence
• AI can produce writing and pictures but cannot produce program code.Artificial intelligence
• It is often hard for a person to see on what grounds a deep learning model produced its answer.Artificial intelligence
• Once an AI model has finished training, its performance stays the same even as the world around it changes.Artificial intelligence

• Which data structure stores values of one kind in a single row, each given a number?Algorithms
• Which sort is named for the way small values rise to one end like bubbles?Algorithms
• Which sort works like picking up cards one at a time and slipping each into its right place among the cards already arranged?Algorithms
• Which data structure lets you add and remove items at both the front and the back?Algorithms
• What is the time complexity of a search that weighs items against the middle value of sorted data and halves the range each time?Algorithms

• Rewriting the same procedure in Python instead of Java makes it a different algorithm.Algorithms
• There is only one algorithm for a given problem, so there is no choice of method to make.Algorithms
• Algorithms are at work when a map app finds a quick route to your destination.Algorithms
• A recipe written out as ordered steps also counts as an example of an algorithm.Algorithms
