1 and 2.
In any word of more than one syllable there is at least one syllable more forcibly uttered. This is said to be stress. Stress (or accent) on a syllable makes it more prominent. Acousticlly, the stressed syllable produces an effect of loudness.
The breath in articulation may be of various degrees of strenght. There are three principal degrees:
i. Primary stress - the strongest on in the word and indicated by a high verticle stroke place immediately before the syllable bearing that stress.
ii. Secondary stress - the intermediate one shown by a low stroke just befoe the syllable.
iii. Weak stress - the syllable of syllalbes not stressed at all and left unmarked.
3. Consonant clusters are groups of two, three or four consonant sounds sid together with no intervening vowel. Examples of words with initial consonants: place, train, clock, spread. Examples of words with final consonants: ask, crisps, tests.
Syllablic consonants are / l, m, n /. They sometimes seem to fulfil a syllabic function without the presence of a vowel. e.g. in middle / -dl / and botton / -tn/. These /l/ and /n/ phonemes can be said to be sllabic here in terms of the prominence and pulse theories; they also function as separate units in the intonation structure of English.

typo mistakes: various degrees of strength (NOT strenght) , can be said to be syllabic (NOT sllabic)
