+*Single sentence*
+
+- **SST-2** is a task for predicting the sentiment polarity of movie reviews.
 
 *Semantic similarity*
 
-- SST-2
-- MRPC
-- STS-B
+- **MRPC** is a task for determining whether a pair of sentences are mutual paraphrases.
+- **STS-B** is a task for predicting a similarity score (from 1 to 5) for each sentence pair.
 
 *Inference*
 
-- MNLI: matched and mismatched
-- QNLI
-- RTE
-- WNLI
-- CB
-- AB: b and g
+- **MNLI** is a task to determine if a given premise sentence entails, contradicts, or is neutral to a hypothesis sentence; this task includes **matched** (in-domain) and **mismatched** (cross-domain) validation and test sets.
+- **QNLI** is a question-answering task converted to determine whether the context sentence contains the answer to the question.
+- **RTE** is a task for determining whether a premise sentence entails a hypothesis sentence.
+- **WNLI** is a pronoun resolution task formulated as sentence pair entailment classification where, in the second sentence, the pronoun is replaced by a possible referent.
+- **CB** comprises short texts with embedded clauses; one such clause is extracted as a hypothesis and should be classified as neutral, entailment or contradiction.
+- **AX_b** is designed to test models across a wide spectrum of linguistic, commonsense, and world knowledge; each instance contains a sentence pair labeled with entailment or not entailment.
+- **AX_g** is designed to measure gender bias, where each premise sentence includes a male or female pronoun and a hypothesis includes a possible referent for the pronoun.
 
 *Question answering*
 
-- BoolQ
-- MultiRC
+- **BoolQ** is a question-answering task where yes/no questions are given for short text passages.
+- **MultiRC** is a task where, given a context paragraph, a question, and an answer, the goal is to determine whether the answer is true; for the same context and question, more than one answer may be correct.
 
 *Reasoning*
 
-- CoPA
+- **CoPA** is a casual reasoning task: given a premise, two choices, and a cause/effect prompt, the system must choose one of the choices.
