Answer 1

matchSentence = ["weather in", "weather at", "weather on"]
sentence = "weather on monday"

maxCount = 0
maxCntInd = -1
words1 = sentence.split()  # list of all words in sentence
wordSet1 = set(words1)

for item in matchSentence:
    ''' here get the index of the `item`
    if all the words are in the `item.split()` is in the `sentence`
    '''
    words2 = item.split()  # list of all words in item
    wordSet2 = set(words2)

    commonWords = len(wordSet2.intersection(wordSet1))
    if commonWords >= maxCount:
        maxCount = commonWords
        maxCntInd = matchSentence.index(item)

print(maxCntInd)
