Explanation:

The word "garrulous" means talkative. In the first sentence, Julian's talkative personality is amusing, which is a correct usage. In the second sentence, the station manager is usually talkative but becomes quiet when asked for sensitive information, which also uses "garrulous" correctly. The third sentence uses "garrulous" incorrectly as it should be "growing" or "ongoing" research. The fourth sentence uses "garrulous" incorrectly as it should be "conductive" materials for electricity flow.
